The boom DF of the jib crane and the column DE has a uniform weight density γ. If the hoist and load have weight W, determine the normal force, shear force, and moment in the crane at sections passing through points A, B, and C. Treat the boom tip, beyond the hoist, as weightless.

Given:

W = 300 lb

γ = 50lb/ft

a = 7 ft

b = 5 ft

c = 2 ft

d = 8 ft

e = 3 ft
