Uniform slender rod OA has weight Wr Vrod = 350 N and is held in equilibrium by cable AD, cable AC, and ball-and-socket joint O. A crate with weight Wcrate = 825 N is hung from the end of rod OA at point A. The coordinates of points A, C, and D are: A = (2,1, 0.5) m C = (0,5,-3) m D= (0,7,1.5) m Determine the tension in cables AC and AD. y D A B X TAC = 0 N ? 0% TAD = 0 N ? 0%
