[numenclature]

thank you for an amazing video. I know its a little complex for grade 1's, but I think they will benefit from the early exposure.

[TheUltimateToad]

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

[Ilovebodyslam2541]

[Lor27509]

Does the cars have gears too?



[Shumaka84]

@Lor27509 of course... what do you think car shifts are for? they change low to bigger gears and vice versa :)

and the connections

etc

(i don't know the exact names once i'm not english but i assure you cars have LOTS of gears :p)

[forsalololo95]

You are awsome!!!!!

[domyaska]

[BogMonkey53]

This is the most informative video I've seen in a long time.

I actually live near those locks here in Ottawa. Now I want to go to them and start asking if I can turn some gears :)

[rozallez]

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

[allgone80]

all the videos by Hila Science are so well organized and presented. thak you so much for putting these together and sharing!

[ArmenFirman01]

thank you so much for your videos! they are great!

[jasongiddensviper478]

Great video it really helped my son. Thank you.

[nayub00]

one of the best demonstration of gears i've seen

[TheNewVideos]

good stuff, makes you want to learn all this.

[chance823232]

great tutorial , thanks !

[dbfs3d]

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.

great teacher

[superpaco1]

informative.. thanks a lots

[inventormoh]

awsome video .

[Maartenn100]

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

[darksideofthebrick13]

this is soo cool! I want to modify my 21 speed to a 28 speed now!

[syedfezu]

great work.

u just make it so easy to understand

[michaeljjeffrey]

This is very simple, BUT it's simply brilliant. I love this video - GREAT WORK !!!

[Jiosonus]

A very good video. I believe all science should be like this. Simple, straightforward, easy to follow along.

[lmeister3]

Awesome

[AdmiralZhao007]

isn't 3:32 the rideau canal?

I've been there

proud to be canadian lolz

[nawara88]

Great Video

[bobsle6ta]

this is one of the coolest videos here

[madvideogamer]

When I was younger I used to have a "Lego Bionicle" and most often they would use gears to do different actions, that got me very interested.

[caveman600v2]

same, but i'n still young :)

[AdmiralZhao007]

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...

[PerfectParasite]

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

[twilightvengance]

wouldn't it be faster to wind a big gear connected to a small gear rather than the other way around? I am sorry but to me that makes a little more sense.

[jmh11962]

What a great video! this is some really good stuff that you are sharing. the U.S. needs more of this kind of stuff out there to prevent the "brain drain"

that seems to be plaguing our young people!

[Btony09]

your videos are always so informative

[mop6wewe]

thanks im makeing a new motor bike that helped alot

[M3n747]

Thanks a lot for this video - up until now I just couldn't comprehend the relationship between front and back bicycle gears.

[wis2k]

great n very interesting

[krcrange]

nice like always

[john3167777]

nice video

[GeeKayKayGee]

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.

[random414]

Extraordinary as always! ;)

[SnakeEyes1337]

another nice vid
