The 12ft pole AC (negligible mass) lies in the y-z plane and forms a 30° angle with the z-axis. The pole is held in place at point C by a ball-and-socket joint. Two cables, BD and BE, are fixed to the pole at point B (these represent two separate cables attached at B). A 110 lb force pulls downward at the end of pole AC in the vertical direction (y-direction). If the distance between B and C along the feet, determine the Reactions at C (ball-and-socket joint) The tension in cables BD and BE.
