The system shown below is in statics equilibrium. Cable OB lies in the xy plane and makes a 30° angle with the positive x-axis. Cable OA lies along the negative y-axis. If the weight of the load being supported is 100 lb, determine the magnitude of the forces in all four cables: OA, OB, OC, and OD. Z A C 8 ft 6 ft O 30° 3 ft y x B D 6 ft
