Calculate the mechanical advantage of a lever that has an input force of 15 N and an output force of 60 N. *

Explanation:

Given that, .

Input effort is 15N

Fi = 15N

Output effort is 60N

Fo = 60N

Then,

Mechanical advantage(M•A) is the ratio of two forces, and it is also referred to has force ratio.

M•A = Output Force / Input Force

M•A = Fo / Fi

M•A = 60 / 15

M•A = 4

The mechanical advantage is 4
