Again we tried to select the best tutorial for you - making the principle of gears understandable for everyone!
This time, our favourite is an article from www.explainthatstuff.com:

GEARS

"Have you ever tried pedalling a bycicle up a really steep hill? It's pretty much impossible unless you use
the right (low) gear to increase your climbing force. Once you're back on the straight, it's a different story.
Flick to yet another different (higher) gear and you can go incredibly fast: you can magically make your
wheels turn round much faster than you're pedalling. Gears are helpfull in machines of all kinds, not just
cars and cycles. They're a simple way to generate more speed or more power or to send the power of a
machine off in another direction ..." Continuation here 

And now that hopefully the principle of gears has become clear, here's the fitting video, showing on a cut-away
model how exactly the gear box operates in a car. Enjoy!
