Gear Basics 

this guy is a walking school you videos are awesome in 11 minutes i learned the same as 1 month in school... you would be a good teacher

I hope ScienceOnline will make more vids exactly like this. It's very good explained! Thanks a lot. (From Europe, Belgium).

This helped me realize how to achieve greater potential with a generator running on water turbines. Very informative, thank you.

So clearly explained. Great narration and examples used.

Awesome video, very well done. Would love too see more videos from this man.

These videos are the reason I'm on RU-vid.

this is one of the safest places on youtube xD

Really helps with me on Robotics

Man its really amazing you explained everything so easily

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)

Another pleasing production from Hilaroad. Gearing and linkage design is I think, a fascinating topic. For those who might be interested this video here on youtube /watch?v=eAniA73C6WI shows many wonderfully different gear trains, all designed to achieve the same end result. Thanks very much for all of your videos Hilaroad, the world needs more teachers like you.

Beautiful presentation.

Awesome ,Very well done.Thank you for taking the time to post .

So, to have optimum speed you need a Big gear on the pedal and a small gear on the wheel?

Guy can help me on this 3 question?1)What are the names of the two rivers that the lock connects?2)Why a high mechanical advantage is necessary to open the locks?3)Name the parts of the machine that enable the locks to be open?

My teacher has this video ,but I don't understand about gear , who can explain me !? I will so happy if I pass my test about the Gear . I'm Thai , if you're Thai people you can explain me in Thai language ,but u are other nation ,don't wory I can read . THANKS PLEASE!!

oh yeah!! i remember that! like the first toa that came out, you could spin a stick in the back, and both their arms would move, or to do a chopping action, or other things like that. ahhh..those were the days...
