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.

Hayley Lever in line, form and color. If I were confined to my own back yard for the rest of my life, I'd still have more pictures in my mind than I would have time to paint. Art is nothing but having a good time." Lever went to Pittsburgh in 1922 as an art juror for the Carnegie International exhibition.
