The operation of the fuel pump for an automobile depends on the reciprocating action of the rocker arm ABC, which is pinned at B and is spring loaded at A and D.
The vertical force acting on the rocker arm at A is FA
= 50N, and at C it is Fc = 150N.
When the smooth cam C is in the position shown, determine the magnitude of the force at B
