Gears: Educational Links

So, I’ve been reading up about cogs and gears – partially so I can connect up my little engine to something, and partly because it’s just generally interesting to learn about. I’ve discovered the various kinds of gears, what they’re used for, what a gear ratio is, how a pendulum clock works, and then played with The Incredible Machine a little, so I could have a go of the gears and belts. For those who may not have encountered The Incredible Machine, it’s a puzzle game that seems greatly inspired by both the game Mousetrap, and Heath Robinson-like devices (or Rube Goldberg, if you’re from that side of the pond).
I thought I’d add the links here for the various pages I’ve been to – in case you to would like to learn more about gears yourself.
