- Thanks for SHARING with your Fzx Teacher!
An introduction to gears from the simple machines perspective. Which are force multipliers? Which are speed multipliers? How do we calculate mechanical advantage?
This was an _excellent_ beginner introduction. I say that as an absolute beginner. Thank you so much. Fun, simple and perfectly clear. Thank you again.
I've been searching for videos to understand about gears and all I saw was scientific stupidity. ....lol until I saw this one, thanks very much you're a real teacher
lolol
Thanks. I thought the same and I like to simplify. There are some other good ones out there but I like mine the most.
What u said that absolutely right bro
What do you mean by scientific stupidity?
@@miguelitoantonio1950 we teachers tend to get bogged down in the tech speak and math oriented interpretation. It works for high end students temporarily but it doesn't necessarily build a long lasting understanding nor does it help the average person. That's how I read it.
6:01 Wow thats amazing. I moved around a lot as a kid so i never got a proper standardized education. Its amazing to see the math used and how simple it is and it gives the imagination something awesome to play with.
I appreciate this video very much.
Thank you! I'm 30 years old and finally getting this idea into my head
Took me a while too!
This was fantastic, but what I really need most is a practical guide to incorporating geears into designs for makers. Common ways to arrange drive shafts and how to pick the best gears to simplify designs and minimize friction. How to decide how many teeth you should have etc. There is so much to know and I don't know where to look!
Straight to the point , easy to understand, thanks!
thanks for watching!
“You just learned physics”, brilliant. I love how simply you broke everything down. They say it takes a genius to explain something complicated in a simple way, so I’m nominating you for genius of the year my friend! 💡
Thanks! Feynman taught me well!
Thanks you explained it really well and helped me understand. Great job!
Thank you for giving me new knowledge about gears , God bless 🙏.

I wish I had you as a professor when I took physics; you made it incredibly easy. I took it over 30 years ago but you have one more sub. Please do Lagrangian and Hamiltonian physics to boot please.
Best gear explanation ever.
Glad it was helpful!
Your explanation was perfect, thank you!
@@geeclan4861 thanks:)
amazing video, nicely demonstrates everything. thank you.
Thanks!
Great demonstration thankyou🙏💯
One of the best refresher I needed today. Having done recoveries during my service, I used to be sharp and quick when it came to calculations of gears or snatch blocks. Not so much anymore. Age is catching up.
I was just told that same "age is catching up" yesterday by a 60 year old friend of mine but I have forgotten things most of my life. In this case it might just be a lack of exposure to the material over a long time and other things to think about. Thanks for taking your refresher course here.
@@LRNFZX Worst is as you explained it, I knew exactly what you meant and where you were going with it. It's like the dust was being blown, on once a smooth polished surface, which once reflected my clarity. Life running its course. LOL
In 6:1 gear ratio, divide 72 by 12, and it equals 6, so you would know that the small gear is 6x faster than the large gear, this is useful if you are going to make something like a pedal spin dryer, which doesn't consume electricity, so you can increase the speed more and more.
Beautifully designed and explained
Thanks!
Gears, ramps and pulleys have one thing in common - they trade distance for power. That's the essence of what I've learned. Gears of course have other uses such as timekeeping, synchronization of machine parts, measurements etc.
Im glad to find this great explanation
I'm glad you did too.
About the 10th time I've watched this video 👍 Got the most out if it so far... 95% there
DAMN GOOD 👍
thanks for watching. Get out there and play with some gears so you get a better idea.
As a 12 year old this video is very helpful I’m playing a game called scrap mechanic and making a piston engine and wanted to learn about gears to help thanks
I've watched so many videos and this one the one that did it foe me and made me get it
Such a valuable information you gave me sir in this video thank you so much 👌
My pleasure
Who else is watching for their OAR? Thank you teacher!

Thanks! Now I understand better my MTB!
that's where I started but it took a long time to understand
I can finally understand transmissions now. That was always the hardest part to learn about in auto class
Glad that worked for you. I'm still getting there on transmissions.

Well done sir very useful thanks
Most welcome
This will help my project success
Get to work! I wish you success.
Thank you very much sir.
You're welcome. Hope you enjoyed it.
This grinds my gears.

Grind me a pound
thank you
Thank you thank you 🙏
Great video, Easy to under Gear ratio (IMA)
Thanks. Gears are pretty amazing.
@@LRNFZX
Sir is their way of Calculation the Gear Ratio (IMA) for Geneva Mechanism
unfortunately, I'm very left brained, and I suck at mathematics. However, your explanation is very concise. Thank you for simplifying it as best you could. It's very helpful in what I'm trying to accomplish.
That's my goal and I'm glad I accomplished it for you.
Very good job.
Thank you!
hello, my question is if I have a target torque X N.m, and Y rpm for my driven gear, how do I pick motor for the driver so that input is enough ? Do i start by using whatever gear ratio to find appropriate torque input?
I love this video
Thanks!
That really helps thanks!
Thanks for watching

Best physics teacher I had 505k views
Idler size don't matter.. that's a very nice thing to learn.. thanks!
and thanks for watching!
this is also useful when you are making cranes. it's going to be alot slower but you can easily lift. also useful for exercising. who knew changing gears can change the whole mechanism
Special Dude - exactly
have you seen this video. with some smart placed gears you can lift insane amout of weight ua-cam.com/video/pvE83NfbZ8g/v-deo.html
and theres also this video. spinning a wheel insanely fast using a gear and a motor ua-cam.com/video/zJ3TABb1MRY/v-deo.html
and theres also another video that makes the wheel go even FASTER
I hope we can discuss springs cause when there is a 10:1 on a spring
If the sprimg moves once and the next gear moves 10 times the gear moving 10 times definitely is not 10x weaker
So if I am trying to multiply torque does that mean if I have a small electric engine that has an output of 0.15Nm continuous torque and I set up a gear ratio of 3 then the ending output torque is just 3x my 0.15Nm or 0.45Nm?
good video👍
Thanks for the video it definitely helped me gain an understanding of them, as far as making sure 2 gears are compatible and will mesh together what do you need to look for?
What kind of gears? Directly meshed? Driven by a a chain?
@@LRNFZX spur gears, directly meshed, driven by an electric motor or hand crank
@@heavyfeather6682 - heavy feather - so you don't want the motor to spin too slowly since it will draw huge currents. And you need to consider your desired output speed. Once you know your motor and have the information on the best motor speed and your desired output speed you can calculate the gear ratio and then look for gears that work for your application.
I am currently looking at my motorcycle and the first gear is too high. I have to slip the clutch a lot and rev the engine way too high so I need a lower gear. The engine input is thousands of RPM and the wheel starts at 0 RPM so I have to put a smaller gear on the input shaft to slow down the output.
The only problem is that when I reach high speeds the engine will then be spinning faster for the same road speed. Compromises for this torque multiplier.
The bicycle is the opposite - the foot motor is slow and the bicycle is a speed multiplier.
Nicely done. Clarified some things for me.
Glad to hear it!
Wow super..
🔥🔥🔥🔥🔥🔥👀
THANK YOU
Thanks for watching
Yessir
Please where can I get these wooden gears!!!!
You’re still my favorite high school teacher Mr. D
Thanks, Max. Good to hear from you. Hope things are going well.

Yer weeeeeelcome!
excellent video !
Glad you liked it!
I want to make compound gears ( 2 stages),
3:1 (45:15)
4:1 (60:15)
I want to know how much dieter for each gear?
Where do you buy gears?
The module is physical seen?
U are thne best
Ewe two!
We are starting Physics very soon, I am nervous as I don't have a very good memory especially memorizing Formulas, You have a good strategy ?
Gears are so cool! Here from anime Dr. Stone
nice
Damn you physics ! good explanation!
could you please make more videos about gears, the topic is interesting. What happens where there are multiple gears in serial does only the first and last get affected ? Running multiple gears in parallel?
Excellent idea. One answer - as long as they're all simple gears like these the multiple gears "in serial" will result in the same ratio as just the first and last. I'll take a look at more gears videos.
I was looking for a video that could teach me how gears work so I can make a fan out of gears and I'm really Intrigeed by physics
Fzx is fabulous, isn’t it?
I did it to understand a Minecraft mod xD
@ami ksa haha! I did it because I was thinking that gears are one of the only anchient inventions that is used as symbols on computers and are still used today IRL.
Cool
SCIENCE!!!
can i bother you for the type and thickness of ply you used?
The gears were purchased but the wood was just a scrap from the basement.
i was thinking about gravity-driven generators with enormous gear ratios, stuff like millions of turns to one, wouldn't the force on the final gears' teeth be incredibly huge?
If the output is spinning "millions of times" slower? Yes. Plus the drive system won't be very efficient - too much friction. Generators often spin quickly so you want them to go fast - you might be looking at a speed multiplier where the final gear is smallest and spinning quickly.
i was thinking of this video: ua-cam.com/video/kYmUJVE6Vo0/v-deo.html
i guess they use VASTLY different gear train designs than traditional ones.
That was pretty interesting. Once it gets loaded on the output with any real force that would be tough to turn with all the friction. And they look like foam rollers. Cool concept.
This voice reminds me Classic Game Room
U just learned physics me thats why im here
LRNn Fzx iz wut it’s all about
💖💖💘💘💕💕
thx my teacher thanks you for helping me understand gears-_-
thanks for watching! Glad it helped.
Gears are fucking amazing
Can I get more in PDF form?

I have learned this myself when I was in 7th class from my bicycle.
That's how I started learning too - the bicycle helped a lot.
Saurabh Sunny 👀
I just want to make stuff out of gears, I just learnt how to design them to 3D print
@@Volt64bolt - sounds like fun. To what will you anchor them? What will they drive. Get to it!
I need the gears he used in the vid
They were quite a find and helped me teach gears better
I prefer to call 'dividers' multipliers; just multiplying by a positive number less than 1.
For the worm gear, I counted hat there are more then 20 teeths in the worm wheel. Why does it takes only 20 rotations of the worm gear for one complete rotation of the gear wheel? I thought the number of rotations to give it one complete rotation is the number of teeth.
I had ignored that until you asked so I had to look into it since it definitely doesn't make sense - good observation by the way.
I looked at the thread pitch and it appears that there are three separate threads wrapped on the shaft. it only takes about 3.3 rotations of the input shaft to push my thumb nail from one end to the other even though it counts 10 threads. Thanks for the question - it stumped me for a while.
If the small cogwheel is turning faster, the big one is turning slower because the small one takes a while to reach 360°.
By definition, yes. The linear speed of the teeth of each wheel is the same but the rotational speed is different.
I don't think you mentioned what "IMA" means.
Is that "Inherent Mechanical Advantage"?
Would be simpler to just use MA.
Good video. I'm sharing it.
How would I find the number of teeth for the gears I need from a ratio? I have a ratio of 1:1.25 and I'm trying to find out how many teeth each gear needs to achieve that ratio but I can't figure it out 🙁
That's 1:5/4 so 5:4 or 10:8 or 15:12 or 20:16 etc for number of teeth
@@LRNFZX Thank you so much you have no idea how much you've helped me out there you're a legend!
@@ethaniel_tweedy how much iq do you have? 60?
Bicycles have sprockets. No gears mesh together on my bike. They are joined by chain
And yet somehow bicycles still have "gear ratios" and not "sprocket ratios."
Now i can fullfill my dream to Rebuild the Porsche Maus.
Don't judge me, i love tanks.
