The uniform beam of mass 40 kg is supported by the rope which is attached to the end of the beam, wraps over a rough peg, and is then connected to the 80 kg block. If the coefficient of static friction between the beam and the block is u_s=0.4 , and between the rope and the peg is u_s= 0.5 s, determine: the maximum distance that the block can be placed from A and still remain in equilibrium.
