M Counter weight 0 M Counter weight
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 is
zero. The mass per unit length of the main cable is 10 kg/m and EAo = 1000KN. The
horizontal distance between the two towers is 100 m. The angle del is 60°. By design the total horizontal load on each tower is zero. Find
A)The horizontal and vertical loads exerted on each tower by the main cable
B)The minimum mass M of the counter weights. Note that the counter weights are blocked from moving in the horizontal direction
