A block of weight W is hung from member AB as shown. Neglecting the weight of AB

Question:

A block of weight W is hung from member AB as shown. Neglecting the weight of AB and knowing that the spring is unstretched when θ = 20°, determine the value of θ corresponding to equilibrium when W = 6.6 lb. State whether the equilibrium is stable, unstable, or neutral.
