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 Factory was founded in 1885 by William Hesketh Lever. Lever Brothers Ltd was incorporated in Australia on 21 June 1894. Soon after this, in 1897, Lever Brothers established a plant at Balmain to extract oil from copra which was shipped back to Liverpool, England. In 1900, the Balmain plant began to manufacture Sunlight soap and glycerine, and other products followed. Early in 1914, William Lever visited Melbourne as part of a worldwide tour of Lever interests. During the visit he met with J.Kitchen & Sons, who were established soap manufacturers, and offered to amalgamate the two firms. After consideration, it was
