The boom AC in the figure rests in a ball and socket joint at A and is held in equilibrium by the cables BE and CD. The load applied at C. Determine the coordinates of D in the YZ plane so that the force in CD will be a minimum. Neglect the weight of the boom and cables. Answers: y = 16 ft; z = -34.7 ft Note: The reaction at ball and socket joint is always represented by the x, y and z components.
