Question:

The mobile crane has weight W1 and center of gravity at G1; the boom has weight W2 and center of gravity at G2. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn if the suspended load has weight W.

Neglect the thickness of the tracks at A and B.


Given:

W1 = 120000 lb

W2 = 30000 lb

W = 40000 lb

a = 4 ft

b = 6 ft

c = 3 ft

d = 12 ft

e = 15 ft
