Question

A boy pries a nail out of a wall by applying a force of 100 N to a pincer. The pincer applies a force of 1300 N to the nail. Calculate the mechanical advantage of the pincer.

Answer 1

Mechanical advantage is calculated by dividing the output force (1300 N) by the input force (100 N).

Mechanical advantage = 1300 N / 100 N = 13

Therefore, the mechanical advantage of the pincer in prying out the nail is 13.
