Wheel and Axle

By Camila Andrea

What is a wheel and Axle

A simple lifting machine consisting of rope that unwinds from a wheel on to a cylindrical drum or shaft joined to te weel to provide mechanical advantage. The axle is a rod that goes through the wheel. This lets the wheel turn.When the axle turns, the wheel also turns.

Mechanical advantage

Is the ratio of the force produced by a machine to the force applied to it , used in assessing the performance of a machine .The mechanical advantage is the relationship between the force and distance inputted and outputted by the wheel and axle and is directly related to the radius of the wheel and the axle.

To find the mechanical advantage you need to find the radius of the wheel. After that you need to find the radius of the axle. Than you divide the radius of the big wheel to the radius of the small wheel.
