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 .
Lever Brothers Margarine Unie, to form Unilever, the first modern multinational company. As part of the agreement, Lever Brothers changed its name to Unilever plc, and forms the British half of the dual-listed company. Although the two companies have separate shareholders and stock exchange listings, they have a common board of directors and essentially operate as one company.
