Lever the power out, and the ratio of output to input force is given by the ratio of the distances from the fulcrum to the points of application of these forces. This is known as the "law of the lever." The mechanical advantage of a lever can be determined by considering the balance of moments or torque, "T", about the fulcrum. where F is the input force to the lever and F is the output force. The distances "a" and "b" are the perpendicular distances between the forces and the fulcrum. Since the moments of torque must be balanced, formula_3 .
Little Lever Urban District Little Lever Urban District Little Lever was, from 1872 to 1974, a local government district centred on the large village of Little Lever in the administrative county of Lancashire, England. Little Lever was a township and chapelry in the civil and ecclesiastical parish of Bolton le Moors in the Salford Hundred of Lancashire.
