Question

What is a mechanical advantage?

Answer 1

the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.

Answer 2

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever
