A cable passes around three 30-mm-radius pulleys and supports two blocks as shown. Two of the pulleys are locked to prevent rotation, while the third pulley is rotated slowly at a constant speed. Knowing that the coefficients of friction between the cable and the pulleys are μs = 0.20 and μk = 0.15, determine the largest mass mA which can be raised

(a) If pulley C is rotated,

(b) If pulley E is rotated.
