Two rods AC and CE are connected by a pin at C and by a spring AE.

Question:

Two rods AC and CE are connected by a pin at C and by a spring AE. The constant of the spring is 1.5 lb/in., and the spring is unstretched when Î¸ = 30°. Knowing that l = 10 in. and neglecting the weight of the rods, determine the value of Î¸ corresponding to equilibrium when P = 40 lb.
