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 railway station Darcy Lever railway station Darcy Lever railway station served the Darcy Lever area of eastern Bolton between 1848 and 1951. The station opened on 20 November 1848. It was on the Bury– section of the Liverpool & Bury Railway, which opened on the same day. To the east of the station, the valley of the River Tonge is crossed by Darcy Lever viaduct, which is high. It has eight spans supported by stone piers: two spans are long, and six are long. Each consists of six lattice girders: two , which also form the parapets, flanking four which are deep.
