Answer 1

"The giant wheel is a practical example of a wheel and axle.

Wheel and axle is a type of a simple machine in which a wheel is supported by a rod like structure called the axle.

In a giant wheel which is a famous merry-go-round, the wheel is fixed to a rod.

When the axle is moved, the wheel also starts moving in a circular motion at a high speed."
