Lever is obtained as which is the mechanical advantage of the lever. This equation shows that if the distance "a" from the fulcrum to the point "A" where the input force is applied is greater than the distance "b" from fulcrum to the point "B" where the output force is applied, then the lever amplifies the input force. If the opposite is true that the distance from the fulcrum to the input point "A" is less than from the fulcrum to the output point "B", then the lever reduces the magnitude of the input force.

Lever and Boyle earned pocket-money singing ballads of their own composing in the streets of Dublin and played many other pranks which Lever embellished in the novels "O'Malley", "Con Cregan" and "Lord Kilgobbin".
