Lever fulcrum to where the output force is applied (point "B"), then the lever amplifies the input force. On the other hand, if the distance "a" from the fulcrum to the input force is less than the distance "b" from the fulcrum to the output force, then the lever reduces the input force. The use of velocity in the static analysis of a lever is an application of the principle of virtual work. A lever is modeled as a rigid bar connected to a ground frame by a hinged joint called a fulcrum. The lever is operated by applying an input
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
