The mobile crane has weight W₁ and center of gravity at G₁; the boom has weight W2 and center of gravity at G₂. If the suspended load has weight W determine the normal reactions at the tracks A and B. For the calculation, neglect the thickness of the tracks.

Units Used:

kip = 10³ lb

Given:

W₁ = 120000 lb a = 4 ft

W₂ = 30000 lb b = 6 ft

W = 16000 lb c = 3 ft

θ = 30 deg d = 12 ft

e = 15 ft
