Mechanical Advantage Of A Pulley Worksheet. Physicists quantify the work the system does by calculating mechanical advantage in Newtons, named after Sir Issac Newton, the originator of the laws of motion. A raising system using a combination of pulleys to leverage the force applied in lifting is referred to as a mechanical advantage (M/A) system.

A pulley is a mechanical component that helps in the transfer of motion from a shaft to a belt or rope (and vice versa).
A pulley system gives you a mechanical advantage by making it much easier to lift and move a load than if you did it by hand.
This means that the weight of the object is twice the force required to. It is a wheel on a shaft that supports the movement of a belt or cable along at its circumference. Pulleys use mechanical advantage, similar to levers, to lift up loads.
