SITUATION. The cable of a suspension bridge shown in the figure below runs over a frictionless Dulley on the top of each of the towers at A and B and is fixed to anchor blocks at D and E. The cable carries a uniform horizontally distributed load of w=160 kN/m. The permissible working stress of th gross area of the cable, including voids, is 800 MPa. Unit weight of concrete is 23.4 kN/m³. For this problem = 400m. S = 40m, H = 60m, a = 45°.
