Question
The parabolic cable running between the two transmission towers is carrying a uniformly distributed load of 15 kN/m over a span of L = 20 m with a sag of y = 5 m. The left end of the cable is connected at point F as shown in the spot detail. The protruding members of the transmission tower is to be analyzed assuming pin connection at joints A and K. Given: a = 1.2 m, b = 0.8 m, c = 1.0 m, d = 0.6 m, and e = 0.3 m.
Calculate the following and indicate if in compression or tension for members.
a. Force in member CG, in kN.
b. Force in member GH, in kN.
