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.

Darcy Lever Fogg died in September 1630, the holding had increased to twenty messuages, a water mill and moiety of two fulling mills along with other land in Darcy Lever In 1632 the mesne tenure had changed and Ellis Crompton after two post mortem inquisitions about John Crompton (his father), held Darcy Lever directly. By 1665, the Bradshaws had taken a considerable parcel of land for their estate. It is not sure how John Bradshaw (died 1662 ) and his wife, the daughter of Robert Lever, (who had purchased some land from Chisnall) came about the land but it can be assumed
