A screw jack acts as a ____ multiplier.

Open in App

Solution

A screw is an inclined plane wound around a rod spirally making a number of turns on it.
$Mechanical advantage = \frac{Load}{Effort}$
A very less effort lifts a heavy load. So M.A > 1. So force is multiplied.
Hence, the screw acts as a force multiplier.
