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.

Little Lever only large house in the village which contained 9 hearths. The manor house, Little Lever Hall, built of wood and plaster was destroyed in the 18th century. It was a seat of the Levers in 1567 and after that the Andrews who inherited the Lever's estate in Rivington. There is a record of a coal pit in 1320.
