Pole OA is fixed at its base and is loaded by cables AC, AD, and BE. The tensions in two of the cables are known: Tac = 120 N and Tad = 240 N. If the maximum allowable moment at the pole base is 150 N-m, what is the allowable range of tensile force in cable BE? (Hint: the governing moment of 150 N-m should be set equal to the magnitude of the moment at base O) A Coordinate data (meters) A ( 0, 2, 0) B ( 0. 1, 0) D C (-1.5. 0. 0) D ( 0. 0. -2) E ( 0.5. 0, 1) O ( 0. 0, 0) E
