Horizontal boom OAB with total length 2 = 2 m is held in equlibrium by cables AD and BE and by a ball- and-socket joint at O. A crate with weight W = 675 N is hung from the end of the boom at point B. The coordinates of points D and E are: D= (1.5, 0, 1.5) m E=(-1.5, 0, 1.5) m Determine the tension in cables AD and BE and the reaction forces at ball-and-socket joint O. You may neglect the mass of the boom in your analysis. When reporting your answer for the reactions at O, use the following sign convention following the coordinate system in the figure: Ro = (Ox)i + (O)j + (O)k.
