- Consider the structure shown in the following figure, which includes two identical towers, a main cable whose unstretched length is 110 m handing between them, and two side cables with negligible weights (so that they can be modeled as massless springs). The side cables are pretentioned so that the net horizontal force on a tower iszero. The mass per unit length of the main cable is 10 kg/m and EAo = 1000KN. Thehorizontal distance between the two towers is 100 m. The angle del is 60°. By design the total horizontal load on each tower is zero.
