Question

Wheel is not a simple machine. What will you do to make it into a simple machine? What is such a machine called?

Answer 1

Answer:

A wheel can be turned into a simple machine by making a wheel and axle arrangement. This forms a class I lever. A wheel or an axle separately do not form any simple machine. One such example is a pulley in which a wheel is present on an axle or shaft that helps in movement or in changing the direction of the force.

Answer 2

Answer:

I would join an axle to it.

This simple machine is known as wheel and axle.
