Question

How a lever can use as a force multiplier

Answer 1

Levers, such as this one, make use of moments to act as a force multiplier . They allow a larger force to act upon the load than is supplied by the effort, so it is easier to move large or heavy objects. The longer the lever, and the further the effort acts from the pivot, the greater the force on the load willbe.

Answer 2
