Question

What two quantities does mechanical advantage compare?A. Input force and output forceB. Input work and output workC. Output force and input workD. Output work and input force

Answer 1

Given:

The mechanical advantage

To find:

What two quantities does mechanical advantage compare?

Explanation:

Mechanical advantage is the ratio of the output force to the input force.

So,

$MA=\frac{Output\text{ force}}{Input\text{ force}}$

Hence, mechanical advantage compares the Input force and output force.
