he cable of a suspension bridge, shown in Figure, runs over a frictionless pulley on top of each of the towers at A and B and is fixed by tension anchor at D and E. If the cable carries a uniform horizontally-distributed load of 120 kN/m, design the cable and towers. For the cable you will need to select the appropriate material, profile and cross-section to achieve an overall safety against tensile failure equal to 3. For the towers you will need to select the appropriate height, materiel and cross-section to achieve an overall safety against tensile failure equal to 3.
