The LEVER is a simple machine whose function is to transmit force and displacement. It consists of a rigid bar which can rotate freely about a support called a fulcrum. The longer the side on which the person exercise force, the greater the multiplying said force, generating a counterbalance force equal to or greater than that exerted by the acceleration of gravity on the object to move. This will accomplish the object and lift raise with very little effort.
Archimedes once said “Give me a place to stand, and I shall move the Earth.” While the idea of a person moving such a huge mass on their own might sound impossible, chances are you’ve seen this idea in action at your local playground. Andy Peterson and
