Determine the tension developed in cables OD and OB and the strut OC, required to support the 500-lb crate. The spring OA has an unstretched length of 0.2 ft and a stiffness of kOA = 350lb/ft. The force in the strut acts along the axis of the strut.
[A]. Fob = 289 lb, Foc = 175.0 lb, Fod = 131.3 lb
[B]. Fob = 86.2 lb, Foc = 175.0 lb, Fod = 506 lb
[C]. Fob = 375 lb, Foc = 0, Fod = 375 lb
[D]. Fob = 664 lb, Foc = 175.0 lb, Fod = 244 lb
