3-30. The 5-ft-long cord AB is attached to the end B of a spring having an unstretched length of 5 ft. The other end of the spring is attached to a roller C so that the spring remains horizontal as it stretches. If a 10-lb weight is suspended from B, determine the angle of cord AB for equilibrium. 5 ft 5 ft A 0 5 ft B k = 10 lb/ft C 3
