Part A The device shown in (Figure 1) is designed to exert a large force on the stationary object at the left. The jack exerts a 225-lb upward force at B. As a result, the link BC exerts a force on the fixed support at C that is directed along the line from B to C, and the link AB exerts a force on the object at A that is directed along the line from B to A.
