I think the reason this explanation is so good is that it approaches the differential not only from a “ here is mechanically how it works” but a “ here’s the problem that each piece solves” as well.
@Revelation 13:4 6:04 - 6:36 "..in order to reduce the jerky action caused by wide spaces between the spokes we will have to add more spokes. Further filling in the spaces between the spokes gives steadier, continuous action, and changing the shape gives firm, continuous contact. Now we can make the gears thicker and stronger." It is correct however that they do not appear to address the "increased durability" statement. My _guess_ would be that a reduction to impact and increased contact between parts would mean that they would last longer (a lighter tap vs heavy thud) but I don't know enough about the mechanics of it to say for sure.

+Tele Blues Man Nah, plenty of people still know how to keep it simple. I won't get many upvotes for saying it, but take a look at the Republican primaries in the US. Notice how Donald Trump keeps speaking simply and plainly so everyone understands him. That is one of the reasons why he is so popular.

But what happens when one wheel is lifted off the ground? It will spin freely while the other wheel on the ground gets very little torque. This surely gets people stuck in snowy situations.
@@sqlexpThis is why limited-slip differentials exist. The one in the video is a simple open differential, or 100% differential, since it allows each wheel to spin independently at any speed.
no the engineers weren't ahead of their time. its everyone else that's behind. its really not hard to pick up a book and learn something or to experiment on your own. most people are just lazy and want to enjoy others hard work.
We just don't teach like this in class or college anymore. Only way you'll get such a full explanation and reasoning on something like this is to personally know someone who actually understands it and wants to help you or finding a good UA-cam video.
Forget about the differential, this is a masterpiece of education. Such an elegant and simple way of explaining this so that literally anyone on the planet could understand it. If schools were as good at teaching as this video is, the world would be full of geniuses
Nowadays tertiary education is just some researcher forced to teach lessons. So they stand up and read some slides, the students go on and teach themselves. Educational material that are clear and concise like this are seen as spoon feeding.
@@jessebeegee If it were that simple, we wouldn't be having dozens of the best-funded public schools in the country failing to produce a single student who can pass their math exams.

Well I'll be damned ... I've always known the function of the differential, but it took a General Motors 16 mm film clip from the 1930's to explain simply and clearly how the dang thing works. Keep in mind, folks, these film "shorts" were viewed in movie theaters before the main movie - there was no T.V. in the 30's.The reason for the motorcycle stunt team at the beginning was to add an element of entertainment to the film.
I let's not forget to support artist and such now a days everyone just want to use as little money as possible. now most art people have at home is copied in the thousands and bought at Walmart, instead of supporting a local artists.

I had one or to professors like this guy (not in engineering but economics), they could make it so simple and engaging, then there was the 'other' type of professor (the like that never left an education Centre), who was no doubt extremely cleaver, but had zero personal skills, just expected everyone to understand what he was talking about from day one. That guy spent the whole lecture with his back to you writing numbers on a board, losing 9/10s of the class. I think it was Einstein that said somthing similar to "if you can't explain somthing simply, you are yet you master the subject" This guy has it nailed down (or did).
LOL omg asking the real questions! Never thought about saving it, and with politics nowdays its possible we need to carry these usefull informations to next humanity
I really appreciate that they started explaining it by introducing a really basic version of the differential. Having the absolute simplest concept of things as a ground to stand on for our comprehension really makes everything easier to understand by people of all levels of intellect. I thoroughly enjoyed this.
Yeah I agree. Seeing something in its full and finished version often overwhelms the mind. But if you see it step by step in a basic way, you can then move on from there with relative ease. This is by far the best video on how a differential works.
The showing of progressively more & more spokes, morphing into sprockets, then gears, really hit the principle on the head of what's happening. This is an excellent verbal and visual explanation.
It was probably a series of simple steps when they understood the problem they had, the solution they needed, and what they had to work with. Think of this riddle: "Question: How do you eat an elephant? Solution: One bite at a time". Many seemingly impossibly complicated problems can be solved when you break them down to a series of small, simple problems.
The conventional automobile differential was invented in 1827 by a Frenchman, Onésiphore Pecqueur. It was used first on steam-driven vehicles and was a well-known device when internal-combustion engines appeared at the end of the 19th century

Its amazing how these people back in the day where able to make high quality videos like these with animations, transitions, and overlays with little to no computer power. Its also pretty interesting how a video from the late 30's is still relevant today
No wonder so many people liked tinkering with cars back then, these films really simplify the principles while also explaining its mechanics and composition profoundly well.
Also remember, that it was all so new and exciting then. So many new mechanical principles. Nowadays it's often about how many microchips and micro-transactions you can stick inside a product. xD Man I do miss the "robustness" of those good old days.

We tend to believe man was less creative in the past. But the way of thinking of a man from the pyramid building time and a man nowadays, is exactly the same. Same creativity, same inteligence. The only thing that improved was the previous knowledge. The problem when teaching things, is jumping basic concepts. The more the teacher jumps, the more difficult to truly understand, no matter if it happened 4.000 years ago or nowadays. That is why we always had and will have good, and not good teachers. The guys that wanted to teach how a transmission and a differential work in this video was a good teacher, with excellent didactic.
This video absolutely blows every other video explaining differential steering totally out of the water in terms of explaining it. Even the most current 3D modeling programs that you see used by modern creators trying to explain this concept don't come anywhere close to being as affective as this simple demonstration. I mean, I watched like three other videos on how differentials work, and they were all beautifully modeled in a computer program and looked great, but none of them really made it click with me like this video did. The beauty is in the simplicity, I guess. Either way, this video was able to really let me wrap my mind around how this all works, and it's pretty awesome that it was made so long ago.
brief? dude there's like 3 minutes of dudes riding motorcycles in circles at the beginning, are you smoking crack? actually i realized that was a dumb question can i have some of your crack? because your definitely smoking a lot of that good good fucking shit
This is great It doesn't just explain how it works, it also explains why a differential was necessary in the first place and does it with simplicity 👍😉
Except for one thing - a regular differential still only give you a one wheel drive car when it matters as the power will always go to the wheel with the least resistance. Now we need a video on the limited slip differential!
@@nickh5081 I believe open-type differential were either the only type, or the most common differential at the time this video was made. As you said, open-type differentials are fine for spinning on roads, but still a issue when driving on bumpy roads or off-road.
Why is it that all of these old videos and documentaries are so informative and without any fluff. I've recently been watching a lot of old black and white documentaries about machines. They are so informative and to-the-point without any fluff(excessive build-up of information). Most of the videos I sees nowadays have more to do with the person showing there face and talking loudly for half the video and then maybe they'll give some decent info, if not follow it up with "click the link to checkout my course". It's like they just want publicity and not to put forward the solution for problems.

@@lastmanstanding2622 this video isn't education. It is learning. The op _learned_ how a differential works, he wasn't _educated._ Education is political. Learning only cares about reality. Avoid education. Pursue learning.
@@forestdenizen6497 According to the American Heritage Dictionary, their definition of "Education" is as follows; "2. The knowledge or skill obtained or developed by a learning process". I understand the point you are trying to make here, however, you are splitting a very fine hair my friend. Learning and Education are related. For example, can you be considered educated if you haven't learned anything?
it's the style of learning and what people thought mattered back then and today. In my engineering courses the focus is always on the derivations of things, the grand concepts, but rarely are we simply taught how something works in practice. Worse we get basic info, variables, eqs and have to teach ourselves the complicated stuff. I wish we taught things more simply, less theoretical and more practical since that's what's needed today, there are phds and other people who can work on improving concepts and theories, but we need a hands on workforce who can the job, then we can focus on the inner details. teach the simple stuff first basically, not last.
People don't get more intelligent, we just get to know more things that we use for discovering new ones because intelligent people from the past had make out them.
Best differential explanation I’ve ever seen…far better than many modern computer animations that attempt to explain a conceptually difficult, but in practice fairly simple idea.
Its simple really. General public was not as technologically educated as we are today. Now these lazy bastards that educate just assume everyone knows everything, and would rather tell to look it up online than do the teaching themselves.
My Master (as in, the guy who trained me in my field. Not sure if that term is actually used in english?) used to say: Good, reliable technology is always simple. The more moving or electric parts (including sensors and all that) the more likely that something is gonna screw up. For a bit of context (and a little anecdote to prove him right): Our company was responsible for the street lights in my town, and we were in the process of excanging good old Vapor lamps with some more newfangled high-tech lamps (some streets even got LEDs). The Vapor lamps had a coil that acted as a limiter (similar to a resistor), and that's it. The newer lamps had some complicated electronics, including a ~30€ circuit board. (The Coil for those vapor lamps would cost 4€ I was told...) In the year that I did that particular job, I had to exchange countless amounts of those circuit boards. They broke left right and center, and you could always SMELL it as soon as you opened the case they were kept in... (I hate that smell.) Also keep in mind the company had just begun installing these maybe half a year before I joined them. The Vapor lamps? Maybe five coils the entire year. And we had 10 times more of them than the new ones at that point.
Sapphire EX LED lamps are pretty simple too. The problem: companies that produce them are programming them to stop working at certain time. In fact led lamps, on good quality can last more than 20 years.
You'll be surprised to hear why they sound similar. They're all imitating the "Transatlantic Accent". It was used as sort of a standard in the industry to maximise the efficiency and clarity of speech.
@@michaelbienicewicz2993 To be fair this is just one of the highest quality videos in general. It even beats out a lot of the stuff from Vsauce, Kurzgesagt, Veratasium, and 3Blue1Brown.
The differential is a piece of engineering that looks so damn complicated but the principles behind it are astonishingly simple. The person who thought about it for the first time must have been a freaking genius. Btw this 70 yo video is the only one I've ever found that explains it in its pure simplicity and genius.
It was invented by the Chinese for ceremonial reasons or to instill awe in the simple subjects . On a cart a statue would always point in same direction when the cart turned a corner .
His name was Onésiphore Pecqueur, he was french, and he invented it before cars existed (He died 30 years before the first car ever was built). It was originally used on mechanical watches to allow two gears on the same axis to rotate at different speeds. The creativity of old watchmakers is always mindblowing
if school taught like this, the world would be 100 years ahead of its time, we really need to bring back the simple beauty of visual learning in this way. and we should also bring back this gentleman's calming easy to understand voice, i have learned more in 30 minutes of videos like these than i have in 10 years of school. it is truly saddening to see that the best form of education was lost around 70 years ago.
My tutor showed it to my class in college when we were learning about differentials. When he was learning his tutor showed it to his class (I suspect that past tutor also learned about differentials from this video)

Kind of sad, but it was purposely done. By both the government and the auto industry during the 1960's. (and not really for any super conspiracy, shadow government weirdo, NWO shit either.) The industry nearly collapsed due to several factors at that time. Some of the biggest being, the predicted purchase turn around of consumers, and the open sourced 3rd party auto parts, tools and their availability. It was assumed in early forecasts in the auto industry that the average customer would replace their vehicles every 3-5 years. Thus the industry build itself around that model. However, because of growing public knowledge on repairs, Maintenance and availability of parts and tools. The 3 year prediction was off, waaaay off, and the average consumer owned their vehicle for 10+ years. Which led to MILLIONS & Millions of factory automobiles just sitting there, rotting, and often being scrapped (an interesting side effect being, some of the fist reclamation and recycling facilities began as a result of this) About half of the auto producers went under, others forced to consolidate. In response, the auto industry stopped this kind of stuff. Then made many materials, parts and advancements proprietary and trademarked, informed engineers to deliberately build designs that where complex and difficult to repair without formal training or special tools, and lobbied the government to mandate repairmen and auto shops to hold certifications and "mechanic" to be added as a degree program to trade schools and universities. Which they did, nearly collapsing that industry over night as a result, lol. History is so fucking cool. That's a lot of shit, to explain why a video from the 60 years ago is so informative...by comparison to today.
I think because it took time and effort to design and build the physical models (and it probably involved an actual engineer, mechanic, or expert) they also put some time and effort into thinking about how to best use the models for an effective demonstration (with useful simplified explanations). But these days it takes little time and no effort for somebody (utterly clueless about mechanics) to google up some 3D modelling stuff and get the software to put together a really slick-looking yet needlessly overcomplicated (confusing and distracting) photorealistic computer animation.
Absolutely love how their only two reasons they give as to why having a fast spinning driveshaft running through the cabin completely exposed is 'because it would be inconvenient for passengers' and 'would be awkward for carrying luggage'.
Is nobody going to comment that the centre hump that runs through a car now a days is a thing? Originally in the 50's to now was to accommodate the drive shaft of a rear wheel drive. Even front wheel drive cars still have that hump, for like, no reason.
Because driveshaft will be inside a hollow tube or be covered with something when it's inside the cabin. Engineers wouldn't let that huge of a safety hazard be exposed.
That really true 👌🧐 very well and easy to understand , teachers in mechanical school can't explain 😂 that in 4 years of learn , the 100 years of story of ( spindle ) lol 😂
Single best description of differential ever. If it was this simple to explain all along, how did the ability to say it so simply through the years get lost? Silly.
Back in high school during my senior year graduation practice, some of my friends were on the schools AV club and were coordinating the projector presentation. During the practice we were getting a bit rowdy due to end of year jitters and my friends on the AV club threw this video up on the projector, and I tell you every single senior’s attention was locked on this video, and a the roar of small talk faded as each person was captivated by the function of a differential.

Educational videos like this are timeless! You can show a person who ask how a differential gear works in another 100years and it'll still be just as entertaining and educational.
This is the best explanation of this complicated gear that I can find on the web. The point of this delivery was to clarify the principle behind the differential gear. Creating a 3d graphics model could do the same, but the obsession with the model rather than the learning seems to defeat the intent in the examples I have seen.
Bro, why are all the old videos more educational than new ones. All the other explanations i found were too complicated, but this was so easy to understand
Simply amazing. They showed what can be achieved superbly with limited resources in terms of graphic and multimedia. First they explained the problem with motorbike riders and in the end they explained the results with juggling artists.
5:09 - Moment of enlightenment. I literally don't have words to explain how well made this video is - so much genuine effort went into this so that the explanation is as intuitive and easy-to-understand as possible!

It's similar to how like, you know, how like, people like use the word "like" all of the time to like, get their like, point across? With a like, upward inflection at the end so it like, sounds like a question? Like, you know what I like, mean?
It's a mind blowing to me how when we size up the model and cut a few corners makes everything so understandable. From 4 bars shaped like cross to that gear-I-forgot-the-name-of. The gears looks overly complicated but really it's just efficiently placed 'bars' just tighter and shorter. Or is it just me?
I like it because I believe the sticks model is how Archimedes extended his principals of Levers into multiple continuous levers now known as "gears". With that he then constructed the antikythera mechanism and with his principals we have constructed the world as we know it.
For some reason, these old videos are often the absolute best at explaining these concepts. It's the same with science. If I need to fill in some hole in my understanding of high school physics, there's usually one of these old videos explaining the concept much better than anyone else. Like, what happened to education between then and now?!
Automatically brake one of those wheels and you have traction control. Do the same in the front and add a differential to the “middle” of the driveshaft and you have AWD. Add the ability to lock or brake the pivot and you have a limited slip differential. Be able to lock the front, rear, and center differentials and you have 4x4.
Rejean Rivard That's because conditionally most brains function better when absorbing material in 10-20 min sessions than 60-90 min class periods. After the first 20-30min its normal for a brain to lose focus, so typically if you have a 60-90 min class period the brain absorbs information most efficiently at the beginning and end of class. The stuff in the middle kind of just gets forgotten, so it's not bad to study for 20-30min, take a 10 min break, and then start studying again.

Because .. there are always things you don't know
not only did he explain the basic physical principles, he even explained how the change went from singular bars towards the cogs, this was a great video!
But what happens when one wheel is lifted off the ground? It will spin freely while the other wheel on the ground gets very little torque. This surely gets people stuck in snowy situations.
@@sqlexpThis is why limited-slip differentials exist. The one in the video is a simple open differential, or 100% differential, since it allows each wheel to spin independently at any speed.
My Auto Tech teacher showed our class this and he said this was the easiest explanation ever about how a differential works. Man was he right.

Forget about the differential, this is a masterpiece of education. Such an elegant and simple way of explaining this so that literally anyone on the planet could understand it. If schools were as good at teaching as this video is, the world would be full of geniuses
Nowadays tertiary education is just some researcher forced to teach lessons. So they stand up and read some slides, the students go on and teach themselves. Educational material that are clear and concise like this are seen as spoon feeding.
That's why it is called as school
that’s what happens when education and cinema/arts get public funding. give people money, it’s really that easy!!
@@jessebeegee If it were that simple, we wouldn't be having dozens of the best-funded public schools in the country failing to produce a single student who can pass their math exams. Public funding might be PART of the answer, but it is not the WHOLE of the answer. If it was, the U.S. public education system would not be such an abysmal failure that we'd actually be doing the kids a favor by shutting it down.
Before, even encyclopedias was more comprehensive. I read three editions of Big Soviet Еncyclopedia, and in the edition of 1937, one could read how to make explosives, powder and guns.
85 years later, this is STILL the BEST explanation of differentials!

And most of all... it doesn't insult our intelligence by demanding 'click to subscribe' before we've seen if the content is worth beans. I've arrived at the point where if that's how a video opens, I will definitely not subscribe even if I like the presentation.
Well I'll be damned ... I've always known the function of the differential, but it took a General Motors 16 mm film clip from the 1930's to explain simply and clearly how the dang thing works. Keep in mind, folks, these film "shorts" were viewed in movie theaters before the main movie - there was no T.V. in the 30's.The reason for the motorcycle stunt team at the beginning was to add an element of entertainment to the film.
Not merely to add entertainment, but to grab everyone's attention so they'd watch the rest of the film strip.
I don't see that on Americas Got Talent, amazing how bold men were back in the day. My testosterone rose 10 points just watching that.
this video itself was entertainment!
I let's not forget to support artist and such now a days everyone just want to use as little money as possible. now most art people have at home is copied in the thousands and bought at Walmart, instead of supporting a local artists.
It’s the 30’s, why wouldn’t there be an absurd stunt bit?
No CGI, no special effects, no BS.
We should salute our early engineers and designers and those who followed them.

People like this guy are truly rare. People that can pass on their knowlage with ease.

That guy spent the whole lecture with his back to you writing numbers on a board, losing 9/10s of the class.
I think it was Einstein that said somthing similar to "if you can't explain somthing simply, you are yet you master the subject"
This guy has it nailed down (or did).

I really appreciate that they started explaining it by introducing a really basic version of the differential. Having the absolute simplest concept of things as a ground to stand on for our comprehension really makes everything easier to understand by people of all levels of intellect. I thoroughly enjoyed this.
Yeah I agree.
Seeing something in its full and finished version often overwhelms the mind. But if you see it step by step in a basic way, you can then move on from there with relative ease.
This is by far the best video on how a differential works.
yeah, i feel like that's the most effective way to teach/explain something
And they show iteration by iteration how it evolves to close those gaps to the more "complex" system.
Thats what happens when someone who truly understands how something works and is able to not only build it themselves but explain it to others.
I really wish this could applied in general teaching.. i wonder how the programming analogue for this would be. hello world?
The showing of progressively more & more spokes, morphing into sprockets, then gears, really hit the principle on the head of what's happening. This is an excellent verbal and visual explanation.
whoever invented differentials was a genius. so simple
It was probably a series of simple steps when they understood the problem they had, the solution they needed, and what they had to work with.
Think of this riddle: "Question: How do you eat an elephant?
Solution: One bite at a time".
Many seemingly impossibly complicated problems can be solved when you break them down to a series of small, simple problems.
No one actually invented it instantly, it's just a process of developing
The conventional automobile differential was invented in 1827 by a Frenchman, Onésiphore Pecqueur. It was used first on steam-driven vehicles and was a well-known device when internal-combustion engines appeared at the end of the 19th century

Its amazing how these people back in the day where able to make high quality videos like these with animations, transitions, and overlays with little to no computer power. Its also pretty interesting how a video from the late 30's is still relevant today
Just good editing back in the days when you had a reel of film, a razor, and tape.
That is a FILM, not a video, and film is much more difficult to work with.
No wonder so many people liked tinkering with cars back then, these films really simplify the principles while also explaining its mechanics and composition profoundly well.
Also remember, that it was all so new and exciting then. So many new mechanical principles. Nowadays it's often about how many microchips and micro-transactions you can stick inside a product. xD

This video absolutely blows every other video explaining differential steering totally out of the water in terms of explaining it. Even the most current 3D modeling programs that you see used by modern creators trying to explain this concept don't come anywhere close to being as affective as this simple demonstration. I mean, I watched like three other videos on how differentials work, and they were all beautifully modeled in a computer program and looked great, but none of them really made it click with me like this video did. The beauty is in the simplicity, I guess. Either way, this video was able to really let me wrap my mind around how this all works, and it's pretty awesome that it was made so long ago.

it's the style of learning and what people thought mattered back then and today. In my engineering courses the focus is always on the derivations of things, the grand concepts, but rarely are we simply taught how something works in practice. Worse we get basic info, variables, eqs and have to teach ourselves the complicated stuff. I wish we taught things more simply, less theoretical and more practical since that's what's needed today, there are phds and other people who can work on improving concepts and theories, but we need a hands on workforce who can the job, then we can focus on the inner details. teach the simple stuff first basically, not last.

No need to reinvent the wheel.

That still isn't a complete rework of the differential. It's just an upgraded version.
My Master (as in, the guy who trained me in my field. Not sure if that term is actually used in english?) used to say: Good, reliable technology is always simple. The more moving or electric parts (including sensors and all that) the more likely that something is gonna screw up.
For a bit of context (and a little anecdote to prove him right): Our company was responsible for the street lights in my town, and we were in the process of excanging good old Vapor lamps with some more newfangled high-tech lamps (some streets even got LEDs).
The Vapor lamps had a coil that acted as a limiter (similar to a resistor), and that's it.
The newer lamps had some complicated electronics, including a ~30€ circuit board. (The Coil for those vapor lamps would cost 4€ I was told...)
In the year that I did that particular job, I had to exchange countless amounts of those circuit boards. They broke left right and center, and you could always SMELL it as soon as you opened the case they were kept in... (I hate that smell.) Also keep in mind the company had just begun installing these maybe half a year before I joined them.
The Vapor lamps? Maybe five coils the entire year. And we had 10 times more of them than the new ones at that point.
Sapphire EX LED lamps are pretty simple too. The problem: companies that produce them are programming them to stop working at certain time. In fact led lamps, on good quality can last more than 20 years.

Thousand times better than today's explainations
That's the truth!
Kind of sad, but it was purposely done. By both the government and the auto industry during the 1960's. (and not really for any super conspiracy, shadow government weirdo, NWO shit either.) The industry nearly collapsed due to several factors at that time. Some of the biggest being, the predicted purchase turn around of consumers, and the open sourced 3rd party auto parts, tools and their availability. It was assumed in early forecasts in the auto industry that the average customer would replace their vehicles every 3-5 years. Thus the industry build itself around that model. However, because of growing public knowledge on repairs, Maintenance and availability of parts and tools. The 3 year prediction was off, waaaay off, and the average consumer owned their vehicle for 10+ years. Which led to MILLIONS & Millions of factory automobiles just sitting there, rotting, and often being scrapped (an interesting side effect being, some of the fist reclamation and recycling facilities began as a result of this) About half of the auto producers went under, others forced to consolidate. In response, the auto industry stopped this kind of stuff. Then made many materials, parts and advancements proprietary and trademarked, informed engineers to deliberately build designs that where complex and difficult to repair without formal training or special tools, and lobbied the government to mandate repairmen and auto shops to hold certifications and "mechanic" to be added as a degree program to trade schools and universities. Which they did, nearly collapsing that industry over night as a result, lol. History is so fucking cool. That's a lot of shit, to explain why a video from the 60 years ago is so informative...by comparison to today.
I think because it took time and effort to design and build the physical models (and it probably involved an actual engineer, mechanic, or expert) they also put some time and effort into thinking about how to best use the models for an effective demonstration (with useful simplified explanations).
But these days it takes little time and no effort for somebody (utterly clueless about mechanics) to google up some 3D modelling stuff and get the software to put together a really slick-looking yet needlessly overcomplicated (confusing and distracting) photorealistic computer animation.

The teachers point of view is that untill it is not complicated enough, it's not worth teaching :P
Unclear 3d animation = less time need to be spent 3d modelling + less time needs to be spend at all + less cost.
Yeah... from one of the largest corporations in America who had an entire art and media division with hundreds of workers.
There's something about these old breakdown educational videos that mesmerizes you.
Wow that 9 minutes flew by
I realised it now that the video is 9 minute long😂. It was hypnotic
Easy...more spokes
Back in high school during my senior year graduation practice, some of my friends were on the schools AV club and were coordinating the projector presentation. During the practice we were getting a bit rowdy due to end of year jitters and my friends on the AV club threw this video up on the projector, and I tell you every single senior’s attention was locked on this video, and a the roar of small talk faded as each person was captivated by the function of a differential.
It just be like that sometimes
That’s awesome (and funny!)
Thanks for sharing!
Everyone gangsta till the teacher put on how cars work.
When you demonstrate it like this it aint boring its *ENTERTAINING*
Yeah if teachers would explain things like this I would love school
I did a restoration on my bosses ‘65 tbird convertible. All mechanical, the concert those mechanisms perform every time you raise and lower the top is truly a thing of utter beauty.
This is the best description of how a differential works I've ever seen.
This is like... really well explained.
i am able to understand without any science background.. amazing tutorial.. God bless the old times
They had blessings for sure...
simple and Easy ,even for indians and africans .....😁
@@theepattikolli there it is, the inevitable comment on race. fuck off, thanks
Educational videos like this are timeless! You can show a person who ask how a differential gear works in another 100years and it'll still be just as entertaining and educational.
I really like how this is explained, it feels so much easier to understand than any modern lecture, text, or lesson.
.....
@@yararahman7055 its the truth!
This is the best tutorial I have ever seen... Great job.
I second this opinion
I've seen many, i mean many old videos, they're so informative, i could watch these for hours, they're so good
Pretty sure the guy you're complimenting is dead
This is the best explanation of this complicated gear that I can find on the web. The point of this delivery was to clarify the principle behind the differential gear. Creating a 3d graphics model could do the same, but the obsession with the model rather than the learning seems to defeat the intent in the examples I have seen.
Өте керемет ағылшынша білмесемде бәрін толығымен түсіндім. Үлкен рахмет сіздерге.
I am blown away with how simple and effective this video is, I didn't even know the rear wheels even moved at different speeds!
Yo tampoco
The front ones as well of course
@@andreasa.2226 I knew the front did, didn't know how though!
@@KHAinnovations menos yo
@@Tencryn the same procedure for the front tyres too but if the vehicle is 2 wheel drive the wheels will be attached separately
What i learned from this:
If something is bothering you, add more spokes!
more is always better
If you keep adding spokes does it then become a " bespoke " wheel?
More spokes we need more and more spokes 🤣😁👍
It's the Kerbal way. There's never enough struts and boosters.
my wife
When life gets hard...... add more spokes.
What a nice thought!! :)
What can be equivalent of more spokes in real-life
Excelent
Spohwkes*.
When life gives you spokes, you make spokenade!
Bro, why are all the old videos more educational than new ones. All the other explanations i found were too complicated, but this was so easy to understand
Wow! This is the best explanation of HOW a differential actually works I've ever seen! Every other only really explains WHAT it does, not HOW.
When an old ad is more educational than the education system
This was an ad?
@@smmb4818 No, it's an old educational short.
@@googleuser3163 well it’s also an advertisement by Chevrolet
I can’t stop watching
Simply amazing. They showed what can be achieved superbly with limited resources in terms of graphic and multimedia. First they explained the problem with motorbike riders and in the end they explained the results with juggling artists.
Well back again, This video never gets old. This is how education should be again. After this the Spinning Levers video.
5:09 - Moment of enlightenment. I literally don't have words to explain how well made this video is - so much genuine effort went into this so that the explanation is as intuitive and easy-to-understand as possible!
You literally don't have words? I'm glad that's clarified. At first I thought you figuratively didn't have words.
@@American-Plague Haha you got me.
@@nirbhay.8400k I'm sorry. Not trying to be a d**k. I just get sick of hearing "literally" being thrown around so much. I've seen 5 comments so far just in OP comments, just in this comment section with people "literally" doing something. It's similar to how like, you know, how like, people like use the word "like" all of the time to like, get their like, point across? With a like, upward inflection at the end so it like, sounds like a question? Like, you know what I like, mean?
@@American-Plague Yeah I get it. Its okay bro.
@@nirbhay.8400k 😎 👍
It's a mind blowing to me how when we size up the model and cut a few corners makes everything so understandable. From 4 bars shaped like cross to that gear-I-forgot-the-name-of. The gears looks overly complicated but really it's just efficiently placed 'bars' just tighter and shorter.
Or is it just me?
That is correct.
Worm gear?
Bevel gear
I like it because I believe the sticks model is how Archimedes extended his principals of Levers into multiple continuous levers now known as "gears". With that he then constructed the antikythera mechanism and with his principals we have constructed the world as we know it.
Spider gear
For some reason, these old videos are often the absolute best at explaining these concepts. It's the same with science. If I need to fill in some hole in my understanding of high school physics, there's usually one of these old videos explaining the concept much better than anyone else. Like, what happened to education between then and now?!
Now educational videos try to look entertaining and engaging rather than getting straight to the point
Now, they actually don't want you getting smart. A dumb society is much easier to manipulate. Especially now we have smartphones.
It's a difficult explanation to give someone without a mechanical clue... this great film solves the problem. I love "More Spokes"!
*My dog keeps losing control running on wet grass, will add more spokes*
Lol
Not more spokes! Get him studded paws
upgrade your dog to beveled gears & an electronic ignition . VVhile you're @ it maybe put a turbo into him
Quad X HAHAHA
you can't use this on dogs
Automatically brake one of those wheels and you have traction control.
Do the same in the front and add a differential to the “middle” of the driveshaft and you have AWD.
Add the ability to lock or brake the pivot and you have a limited slip differential.
Be able to lock the front, rear, and center differentials and you have 4x4.
Nice info....but this video made us addictive to a similar video to explain the points you mentioned.
@e fred What kind of gun is this?
You mean a transfer case. Theres no middle differentials lol

Holy crap! This is quality educational content! I learned more here in 9 mins the in 1 semester of shop class! :P
Rejean Rivard That's because conditionally most brains function better when absorbing material in 10-20 min sessions than 60-90 min class periods. After the first 20-30min its normal for a brain to lose focus, so typically if you have a 60-90 min class period the brain absorbs information most efficiently at the beginning and end of class. The stuff in the middle kind of just gets forgotten, so it's not bad to study for 20-30min, take a 10 min break, and then start studying again.
Ive heard 45 from a 40's PSA.....but kids these days....20 sounds like me hahaha thanks for the info
YES! Yes! I wish they went back to the content they had when I was a kid, not some of the crap they have now. I want Frontiers of Construction and the like, AND THIS!
Discovery is too busy making reality TV to make educational material that takes time, effort, and resources.
Easier to follow some talking head around and film nonsense, then hire a bunch of interns to blotch it all together, dub over some shitty b-grade dramatic music with shit sound effects, and then profit.
+Rejean Rivard lol me too
look at the quality of content. today vs 13 years old content. regardless of time these kind of quality content stays for decades.
