Question: The tower truss has a weight W and a center of gravity at G. The rope system is used to hoist it into the vertical

The tower truss has a weight W and a center of gravity at G. The rope system is used to hoist it into the vertical position. If rope CB is attached to the top of the shear leg AC and a second rope CD is attached to the truss, determine the required tension in BC to hold the truss in the position shown. The base of the truss and the shear leg bears against the stake at A, which can be considered as a pin. Also, compute the compressive force acting along the shear leg.

Given:

W = 575 lb

θ = 40 deg

a = 5 ft

b = 3 ft

c = 10 ft

d = 4 ft

e = 8 ft

Твс d+e A, Ay

d+e A, Ay
