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

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.

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!

“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! 💡

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.

Thank you! I'm 30 years old and finally getting this idea into my head <3

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.

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.

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?

Thanks you explained it really well and helped me understand. Great job!
-
Straight to the point , easy to understand, 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.

Thank you for giving me new knowledge about gears , God bless 🙏.

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?

About the 10th time I've watched this video 👍 Got the most out if it so far... 95% there DAMN GOOD 👍
-
Beautifully designed and explained
-
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?
-
Great demonstration thankyou🙏💯

amazing video, nicely demonstrates everything. thank you.
