The fork lift has a weight W1 and center of gravity at G. If the rear wheels are powered, whereas the front wheels are free to roll, determine the maximum number of crates, each of weight W2 that the fork lift can push forward. The coefficient of static friction between the wheels and the ground is μs and between each crate and the ground is μs.

Given:

W1 = 2400 lb

W2 = 300 lb

μ s = 0.4

μ's = 0.35

a = 2.5 ft

b = 1.25 ft

c = 3.50 ft
