I'm learning about simple machines in school. What's a compound machine?<|im_end|>

A compound machine is a machine that combines two or more simple machines to work together. Examples include a bicycle and a wheelbarrow.<|im_end|>

That makes sense. Can you give me an example of a simple machine in a compound machine?<|im_end|>

In a bicycle, the pedals and wheels work together using simple machines like levers and wheels and axles. When you pedal, you're using a lever to make the wheels turn.<|im_end|>

I see. So, the lever helps make pedaling easier?<|im_end|>

Exactly, the lever helps make pedaling easier by changing the direction of the force you're applying.<|im_end|>
