The articulated crane boom has a weight W and mass center at G. If it supports a load L, determine the force acting at the pin A and the compression in the hydraulic cylinder BC when the boom is in the position shown.

Units Used:

kip = 103 lb

Given:

W = 125 lb

L = 600 lb

a = 4 ft

b = 1 ft

c = 1 ft

d = 8 ft

θ = 40 deg

The articulated crane boom has a weight W and mass
