Hello! How can I help you today?

I'm learning about simple machines in school. What's a compound machine?
user
A compound machine is a machine that combines two or more simple machines to work together. Examples include a bicycle and a wheelbarrow.
assistant
That makes sense. Can you give me an example of a simple machine in a compound machine?
user
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.
assistant
I see. So, the lever helps make pedaling easier?
user
Exactly, the lever helps make pedaling easier by changing the direction of the force you're applying.
