The cables exert the forces shown on the pole. Assuming the pole is supported by a ball-and-socket joint at its base determine the components of reaction at A.

The forces F1 and F2 lie in a horizontal plane.

Given:

F1 = 140 lb

F2 = 75 lb

θ = 30 deg

a = 5 ft

b = 10 ft

c = 15 ft

F2 B -Твс

F2 B - "D
