Example 3.12. The lever ABC of a component of a machine is hinged at B. and is subjected to a system of coplaner forces as shown in Fig. 3.19 200 N 120° 300 N AB - 10cm BC = 12cm Be30° 60 Fig. 3.19. Neglecting friction, find the magnitude of the force (P) to keep the lever in equilibrium. Also determine the magnitude and direction of the reaction at B.
