A wheel and axle is a simple machine consisting of a wheel with an axle through the center of it where a force is transferred from one component to the other.

History

• First documented use by Sumerians around 4000BC
• Mostly used from transportation or pottery

• Wheel and axle was one of the six simple machine identified by Renaissance scientists drawing from Greek texts on technology.

Mechanical advantage

The main advantage of using it is that it reduces the force of friction by using a circular wheel to transfer energy.
