(a) The uniform 50 lb beam is supported by the rope that is attached to the end of the beam, wraps over the pulley, and is then connected to the 100 lb block. If the coefficient of static friction between the beam and the block is µs=0.4, determine the maximum distance that the block can be placed from A and still remain in equilibrium. Assume that the block will not tip. (b) The pulley connecting the block to the uniform beam is replaced by a rough peg. The coefficient of static friction between the peg and the rope is µs = 0.4 also. Determine the revised maximum distance that the block can be placed from A and still remain in equilibrium.

Question
(a) The uniform 50 lb beam is supported by the rope that is attached to the end of
the beam, wraps over the pulley, and is then connected to the 100 lb block. If the
coefficient of static friction between the beam and the block is µs=0.4, determine
the maximum distance that the block can be placed from A and still remain in
equilibrium. Assume that the block will not tip.
(b) The pulley connecting the block to the uniform beam is replaced by a rough peg.
The coefficient of static friction between the peg and the rope is µs = 0.4 also.
Determine the revised maximum distance that the block can be placed from A
and still remain in equilibrium.
