Lever fulcrum to where the output force is applied (point "B"), then the lever amplifies the input force. On the other hand, if the distance "a" from the fulcrum to the input force is less than the distance "b" from the fulcrum to the output force, then the lever reduces the input force. The use of velocity in the static analysis of a lever is an application of the principle of virtual work. A lever is modeled as a rigid bar connected to a ground frame by a hinged joint called a fulcrum. The lever is operated by applying an input
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
