The uniform beam of weight W1 is supported by the rope which is attached to the end

Question:

The uniform beam of weight W1 is supported by the rope which is attached to the end of the beam, wraps over the rough peg, and is then connected to the block of weight W2. If the coefficient of static friction between the beam and the block, and between the rope and the peg, is μs, determine the maximum distance that the block can be placed from A and still remain in equilibrium. Assume the block will not tip.

Given:

W1 = 50 lb

W2 = 100 lb

μ s = 0.4

a = 1 ft

b = 10 ft

W2 W1 Ay b.
