Lever force F at a point "A" located by the coordinate vector r on the bar. The lever then exerts an output force F at the point "B" located by r. The rotation of the lever about the fulcrum "P" is defined by the rotation angle "θ" in radians. Let the coordinate vector of the point "P" that defines the fulcrum be r, and introduce the lengths which are the distances from the fulcrum to the input point "A" and to the output point "B", respectively. Now introduce the unit vectors e and e from the fulcrum to the point "A"
Lever Brothers Factory agreed that Lever Bros would purchase three-quarters of the shares in J.Kitchen & Sons in return for cumulative preferred ordinary shares in Levers. Levers later bought all the remaining shares, and by about 1923-24 fully owned both companies. Shortly after, the company became known as Lever & Kitchen. In 1989, the Home and Personal Care businesses of Lever & Kitchen merged with Rexona in Australia to form L&K: Rexona. The company changed name in 1993 to Lever Rexona and in 2000 merged with Unilever Foods to form what is now Unilever Australasia. At its prime in 1958, the Balmain factory
