It was not really invented it was discovered along with the wheel.
It was Archimedes that mathermatically formulated lever and pulley idea of mechanical advantage by the Use of the Gravitational phenomena.
Archimedes was a Greek who was born in Syracuse,Sicily circa 287 B.C..He used some of his idea for making war machinery. He was the first to invent calculus. He also discovered and formulated the law of Gavitational buoyancy. A law which applies Universally to any medium.
Achimedes would be the One who offficially used the scientific method of experimentation. He is famous for the phrase "Eureka!"
Even though any one in primitve culture with any amount of inteligence had already figured out the Scientific method, way before him.

This sounds like a homework assignment, so I am not going to put it in the format you requested. Yes, the concept of work does explain all of that. Without pulleys, levers, and wedges, we would have to lift 2 ton metal pieces without the use of cranes. You would be so surprised on how many things depend on pulleys, levers, and wedges. J.N.S

Consider this- As work done=Force*displacement. Suppose you have to move a 100Kg stone.Surely,it will be almost impossible for you to do so by only hands. Now take a 10m long lever,and hence Force=Work done/10 The work done is same,but you have to put ten times lesser force,with the help of lever. I hope it is clear now.

Archimedes (287 – 212 BC) is credited with both. These devices were used long before he was born. His mathematical contributions in this area however are unquestionable.
