Compound lever Compound lever The compound lever is a simple machine operating on the premise that the resistance from one lever in a system of levers will act as power for the next, and thus the applied force will be amplified from one lever to the next (as long as the mechanical advantage for each lever is greater than one). Almost all scales use some sort of compound lever to work. Other examples include nail clippers and piano keys. A lever arm uses the fulcrum to lift the load using and intensifying an applied force. In practice, conditions may prevent the use
Darcy Lever was living in 1246, ancestor of the Levers of Little Lever, who held a share of the manor until the beginning of the 17th century. In the Lever of Great Lever are charters referring to the Lever family. Adam de Lever and his son Ellis attested a grant; no. 45. Ellis son of Adam de Lever granted to William his son and his heirs a portion of his land in Little Lever. The bounds began at 'the Langcestre' (alias Hanycestre) where Denebrook fell into the great water called Lever (alias Letoce); ascended the brook to a ditch dividing Little Lever
