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 total of 8s. Several cases were brought before courts by family members trying to take control of the manor. A settlement in 1331, found in favour of Adam, son of Ellis de Lever and the family line was settled. There are no records about the ownership until 1448, when Henry Lever the elder owed rent of 25s (£1.25p) on the village. In 1623 the Bubonic Plague killed a third of the village population. By 1666, the village had sixty hearths liable to tax. Records show the land used for agriculture and the main landowner was John Andrews, who had the
