The Y-type structure is used to support the high voltage transmission cables. If the supporting cables each exert a force F on the structure at B, determine the moment of each force about point A. Also, by the principle of transmissibility, locate the forces at points C and D and determine the moments.
Units Used:
kip = 1000 lb

Given:
F = 275 lb
a = 85 ft
θ = 30 de
