SITUATION. The cable of a suspension bridge shown in the figure below runs over a frictionless pulley 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 the gross area of the cable, including voids, is 800 MPa. Unit weight of concrete is 23.4 kN/m³. For this problem, L= 400m, S = 40m, H = 60m, a = 45°.

6. The wood pole shown in the Figure 4 is supported by two cables of 4 inch diameter. The turnbuckles in the cable are tightened until the stress in the cables reaches 60,000 psi. if the working compressive stress for wood is 200 psi, determine the smallest permissible diameter of the pole. 60° FIGURE 4 60°
