The mobile crane has weight W1 and center of gravity at G1; the boom has weight W2
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
G2 в W2 AB 9. RB

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
