The concrete pipe of weight W is being lowered from the truck bed when it is in

Question:

The concrete pipe of weight W is being lowered from the truck bed when it is in the position shown. If the coefficient of static friction at the points of support A and B is μs determine where it begins to slip first: at A or B, or both at A and B.

Given:

W = 800 lb a = 30 in

μ s = 0.4 b = 18 in

θ = 30 deg c = 5 in

r = 15 in
