A Wheel and Axle:

A wheel and axle is a simple machine that consists of a large wheel attached to a smaller rod, known as an axle. Both parts rotate together to make it easier to move or lift loads.

When the axle rotates, the wheel attached to it also rotates. Electricity, human effort, or any other force can power this rotation.
The axle acts as a fulcrum that supports the movement of the wheel, allowing it to turn smoothly.

For example: bicycles, cars, door knobs, a giant wheel, etc.
