Answer: 180 N

Step-by-step 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

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

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

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