The crate has a weight W1 and a center of gravity at G. If the coefficient of static friction between the crate and the floor is μs , determine the smallest weight of the man so that he can push the crate to the left. The coefficient of static friction between his shoes and the floor is μs. Assume the man exerts only a horizontal force on the crate.

Given:

W1 = 300 lb

W2 = 200 lb

μ s = 0.2

μs = 0.35

a = 4.5 ft c = 3 ft

b = 3.5 ft d = 4.5 ft
