Fantastic couple of teaching videos. Thanks a lot for posting. I just watched them with my eleven year old son, as he is off of school due to the Covid 19 virus. He enthusiastically took the whole lot in. Now he's really keen to make some models with his lego bits.
@@zeroone171 The curriculum was actually made almost 30 years ago, in 1990. 10 years ago is just when they uploaded it to youtube. Of course this only supports your point further though, the other guy was just being a whiny bitch about the noise. I definitely never noticed anything even mildly distracting, much less "unlistenable." Probably just some kid who's only ever listened to audio recorded after 2010 with crystal clear audio recording equipment.
boowonder888 UA-cam. Google. An internet with literally countless websites containing free guides and reference materials all made readily available to anyone 24/7/365?? I don’t think anything good would’ve came from it if I had that type of knowledge at my disposal when I was a kid to where all I had to do was literally reach into my pocket at any given time and pull out a phone to get any question I could ever possibly think of answered immediately. That would’ve most definitely been a recipe for disaster
Nice video , he should mention that when decrease the speed it increases the torque. That's how a car transmission works. When a car starts running it engages the driver gear to the largest driven gear and then starts shifting until get to the smallest one.
I like how giant gears turn tiny gears fast and when you connect another giant gear to the tiny gear, that giant gear spins as fast as the tiny gear. Continue this process a hundred times and you get an extremely fast spinner. One day you could just turn a handle slowly for a minute and get a fast spinning fan for a minute I just love gears
Basics of transmission: 1:1, output will be the same as the input. 1:2, output will be twice the input. So one input rotation will be two rotations of the output. Effectively covering more distance in the same amount of time. Speed is distance x time and so you get a higher speed. 2:1, output will be half the input. How does this multiply torque? IDK, it just works.
A really good video. Gives you a good idea about simple machines. People who cannot applaud the beauty of physics and the brilliance of the human mind shouldn't bother watching it.
Great Video clip! Forgive me for butting in, I would appreciate your initial thoughts. Have you tried - Rozardner Lucky Interview Reality (just google it)? It is a good one of a kind product for firefighter interview tips minus the hard work. Ive heard some great things about it and my cooworker at last got great results with it.
Thank you for this very informative animation. I live in France and I try to teach the operation of the gears to children of ten years. My animation : Engrenages - 1ère leçon (cours élémentaires)
You can try to think of it as relative rotation speed. If red gear is spinning 2x faster than yellow, and yellow is 1.5x faster than blue. How much faster is red than blue? (2red/1yellow)*(1.5yellow/1blue) = 3red/blue, as the yellows cancel in out. Resulting in 3 to 1 ratio red-to-blue.
Nooo.... It's just a random video that you clicked on to look smart while you pick your nose... Yes you're learning! Learning is when you get from confusing to nodding your head in understanding... :o
I've been googling sprokets and v belt pulleys. Looking a struck mini dozer. Bely drive system, trying to build a mini mover but with tires, not hydraulic.drive.. the belt drive mixed in with chain and sprokets... watched a few kit assemblies... then i caught it .... its the chain drive that sets the center (gear) that goes in the opposite direction.. the chain drive runs constantly with the engine, the belts are hooked up to the lower shaft the other to the middle thus the reverser. Quite intresting... I may build it to look like a riding mower, and just say its all wheel steer and all wheel drive. AWDAWS.. THEY MAKE THESE THINGS....
I don't understand why we put the engine on the smaller gear. For example my quadcopter use the small gear for the engine and a much bigger gear for the propeller. That mean that the engine must run really fast to allow the propeller to do one revolution, it's a waste of power no? Because for a bicycle it's the opposite, the big gear is for the engine (the legs) and the small for the back wheel. If the gear of a bicycle would be built like a quadcopter that would mean that we must spin the pedals really fast to do one spin of the back wheel.
The way you connected your engine to the propeller increases torque but decreases speed, if you reverse the gears, the propellers will spin faster, but the torque will decrease..... Personally I think that having high speed is more important than having high torque for a quadcopters, as long as the quadcopter is light and you don't use it for carrying stuff. However, if your quadcopter is relatively heavy, or you want to rig a camera to it or whatever, then you should keep the connections the same, to have a high torque to be able to carry the heavy weight. I hope my reply helped you, sorry if my English is bad, It's not my first language.
I also forgot to mention that high torque is important if you are going to drive your quadcopter in a windy area, because even if the propellers rotate very fast, if you have low torque, the wind will easily manipulate the speed of your propellers making you lose control of your drone
it depends on how much tq your propeller needs. do you know how much resistance the air creates on the propeller? it might need more tq than rpm to create lift. speed/rpm is nice and all, but without tq, you aint moving air
Because the smaller gear is half the size of the bigger gear. Also that smaller gear turns once but because the bigger gear has more teeth it takes longer for the bigger gear to reach what you want it to.
The first wheel was invented in the age of the Flintstones... well it was more like a rounded up square, but they had it :) At least Hannah-Barbera taught me that when i was young ^_^
4:16 wouldn't puting another red gear in the middle keep the ratio and reversing the left red gear? Its like, the same thing he did in the video but with a 24 larger gear...
This is the best video on gear ratios and compound gears, and it seems so ancient.
accurate never gets old
actually, because of the music, it was probably made in the 90's.
Explaining science to kids are the best videos from back in the day.

@@richard102879 It is a disaster. Kids are going nuts and living and dying by their online status. :P
Videos like this make me miss my high school science classes. Thanks for uploading.
Best, simplest & most interesting information on gears ever seen ,read or heard. More videos please. Best appetizers for brain hunger!
Nice video , he should mention that when decrease the speed it increases the torque. That's how a car transmission works. When a car starts running it engages the driver gear to the largest driven gear and then starts shifting until get to the smallest one.
I recommend playing at 1.25x speed. Speeds stuff up a lot..
Good video though!
That was helpful thanks
@@omarmallah5686 lol
Shiv Ahuja no one asked you either.
It didnt speed it up, gear ratios were still the same!
Lol

I just love gears
And that's how grinding stone wheels are made for sharpening tools.
And then connect the contraption with a flywheel to create a longer-lasting fan
You'll need a lot torque on that handle tho.
@Shiv Ahuja force, just search for any insane gear reduction video where they try to rotate the output and it's impossible
Very good description of a spur gear.
Ah yes. I'm finally ready for tomorrow's midterm. :)
*goes to bed*
*shows up to class bright and early*

i really wish my school actually taught me stuff.

thanks i learned a lot my science teacher sucks
Edit: p.s i hate school
this totally helps with my wood shop homework!

Excellent video Sir :)
Explaination is very good ❤
wow my high school physics teacher sucked
Indeed.

There's a 1920, 1930 one, even easier to understand.
I can watch this type of videos for fun!
Excellent. Very informative.
Good video. I love gears.
Finally I can go back and watch transmission videos for I have understood gear ratios :D Thanks!
This video is just excellent.
great video and very clear . l Like this video very much.
GEARS ARE WHEELS
Very helpful, I've been working on something using LEGO and I needed to research how to slow down gear rotation.
Very nice teaching 👍
as the number of gears in compound gear box increases the torque of last gear also increases..
Old is gold
great video!
Thank you for this very informative animation.
I live in France and I try to teach the operation of the gears to children of ten years.

Adding extra gears also adds extra stress to the motor right?
Hope so?
Maybe?
Wonderful and so educative video. Gracias. The Planetary Society, Patagonia, Argentina.
This video is very educational.
Great video 👍
So...a high gear ratio means, essentially, that it takes more time for your out gear to complete a rotation than your in gear.
wow amazing and more efficient than todays videos
I want the book that goes with this video. Anyone know about it; Name, publisher, year of publish? What schools used it perhaps?
Found it, I think if anyone wants it

Byeah.
And I'm just here for fun🤷♂️
Same

Could someone explain why you multiply the two gear ratios together?
because ratios matter
You can try to think of it as relative rotation speed. If red gear is spinning 2x faster than yellow, and yellow is 1.5x faster than blue. How much faster is red than blue?
(2red/1yellow)*(1.5yellow/1blue) = 3red/blue, as the yellows cancel in out. Resulting in 3 to 1 ratio red-to-blue.
good job !
Excellent!
8-5 has now entered the chat. GIRTH
Fun fact: in Norwegian, we call a gear literally for a 'toothed wheel' = tannhjul

Gracias a este video estoy haciendo un pto trabajo de clase xD
LIKE SI VIENES DEL 2020 XD
wow awesome
I am here for school but I am smart I like this
I want to increase the RPM so it was possible to rivers this process ?
Is pulley system and gear system same?
I wasn't a live when this video was made
Get off youtube then.
what do you want a medal for that?
Then why the hell do you have a youtube account.
This video was made in 1990. I get the feeling most of the trolls giving you crap weren't born when it was made either.
Resourceful....it helped me a quite a bit👍
well done!!
Very informative! Thank you very much!
soo gooood
Is there anyway to reduce speed without using gear, belt, chain
Which app use?
This video brought back my memories of courage-the cowardly dog
Thnx for video... It's really helpful
good one.,
Thanks for the video. great help
Nice video , my teacher is used this video to teaches students . I seen it already.
Good luck
Thank you. But do you think you can add other gears than just circular gears? What about corkscrew gears and such.
The Internet at its best!!

+Chad W exactly 👌🏻
if the bigger gear is on the power source and is coneced to the smaller gear the smaller gear will move faster than the bigger gear
What is the name for the theorem explained at 1:40
how can we speed up the movement of those gears in gearbox but with lots of power?
Start with larger gears and move to smaller if a larger gear is moving fast that means the smaller gear goes twice as fast
It's the opposite
Brandon Gibson what about its strength? does the strength levels up?
The strength depends on what kind of gear if you use a lot you can lift a lot but if you have a few good strong ones you won't need as many
😔🧏♀️🧎🏾♀️😭 watching a video from 16 years ago to pass
leonardo da vinci lived in the 1400s-1500s....
Thanks sir❤🙏🖤
Why is it that the toothed gear of 24 teeth moves with half the speed as compared to the gear with 12 teeth......
Because it takes double the time to make a full rotation due to its larger circumfrence
Because the smaller gear is half the size of the bigger gear. Also that smaller gear turns once but because the bigger gear has more teeth it takes longer for the bigger gear to reach what you want it to.
The time does not determine the speed
Wheels. Give em wheels.
The first wheel was invented in the age of the Flintstones... well it was more like a rounded up square, but they had it :)
At least Hannah-Barbera taught me that when i was young ^_^
Good
How to multiply torque?
good !
4:16 wouldn't puting another red gear in the middle keep the ratio and reversing the left red gear? Its like, the same thing he did in the video but with a 24 larger gear...
Sometimes the simplest videos are the best to learn the fundamentals before diving into the depth of machine design
