Suppose you use a machine that gives you a mechanical advantage of 2 to achieve an output force of 30 newtons. what must the input force be? 15 n20 n40 n60 n

The correct answer is 15 N.

Explanation:

The mechanical advantage of a machine is calculated as,

M.A = Output Force/ Input Force

Given, mechanical advantage=2

Output force = 30 N

Substituting the values,

Input force = 15 N

∴ The input force must be 15 N.
