Question: The pin-connected mechanism is constrained at A by a pin and at B by a roller. If P = 10 lb, determine the angle ?

The pin-connected mechanism is constrained at A by a pin and at B by a roller. If P = 10 lb, determine the angle ? for equilibrium. The spring is unstretched when ? = 45^o. Neglect the weight of the members.
