The stiff-leg derrick is supported by a ball-and-socket joint at D and two cables BA and BC. The cables are attached to a smooth collar ring which allows the rotation of the derrick about the z axis. If the derrick supports a crate having a mass of 300 kg, determine the tension in the cables and the x, y and z components of the reaction at D.
