Question

A bicyclist exerts an input force of 15 N on a bicycle with a mechanical advantage of 12. What is the output force of the bicycle?

Answer 1

Answer: 180 N

Explanation: Mechanical advantage of a machine is the ratio of the output force to the input force in a machine.

${\text {mechanical advantage}}=\frac{\text {output force}}{\text {input force}}$

Given: mechanical advantage = 12

input force = 15 N

$12}=\frac{\text {output force}}{15N}$

$12}=\frac{\text{output force}}{15N}$

${\text{output force}}=180N$

Answer 2

The answer is 180, because 15x12=180 <span />
