3.

Determine the tension in the supporting cables BC and BD and the components of reaction at the ball-and-socket joint A of the boom. The boom supports a drum having a weight of 200 lb. at F . Points C and D lie in the x—y plane.

[A].
A_{x} = 0, A_{y} = 150 lb, A_{z} = 562 lb, T_{BC} = 300 lb, T_{BD} = 212 lb [B].
A_{x} = 0, A_{y} = 150 lb, A_{z} = 456 lb, T_{BC} = 150 lb, T_{BD} = 212 lb [C].
A_{x} = 0, A_{y} = 267 lb, A_{z} = 843 lb, T_{BC} = 533 lb, T_{BD} = lb [D].
A_{x} = 0, A_{y} = 150 lb, A_{z} = 500 lb, T_{BC} = 212 lb, T_{BD} = 212 lb
