A cable is placed around three parallel pipes. Two of the pipes are fixed and do not rotate, the third pipe is slowly rotated. The coefficients of friction are H₂- 0.25 and H= 0.20. Given, M = 40 lb. W1 W Determine the largest weight Wthat can be raised if only pipe A is rotated counterclockwise. The largest weight that can be raised if only pipe A is rotated counterclockwise is lb.
