A vertical pole supports a horizontal cable CD and is supported by a ball-and-socket joint at A as shown in the figure below. Cable CD is parallel to the x-z plane (which implies that a vector from C to
D has no y-component) and is oriented at an angle : = 20° from the x-y plane. The distances are given as h = 10 m, b = 6 m, a = 9 m, and d = 4 m.
