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
