Question

The wheel and axle is helpful because it reduces the effort needed to move a load.
What is the "price" you have to pay for this help?

Answer 1

The "price" that you have to pay for this help is by covering more distance

when using it.

Wheel and axle is a type of lever which has three properties present and

they include

• Load

• Fulcrum
• Effort

It helps to reduce the force needed to do work and makes it easier thereby

saving strength and resources. Work done is the product of force and

distance traveled.

Since force is reduced in this type of lever then more distance has to be

covered for work to be done efficiently.
