The homogeneous bar ABCD shown in Fig . 1 is supported by a cable that runs from A to B around the smooth peg at E , a vertical cable at C. and a smooth inclined surface at D. Determine the mass of the heaviest bar that can be supported if the stress in each cable is limited to 120 MPa . The area of the cable AB is 300 mm and that of the cable at C is 400 mm
