A box A of mass M rests on a 50 kg block B, which in turn rest on an inclined plane. The coefficient of friction between boxes is 0.40 and between box B and surface is 0.30. Pulley is frictionless. Determine the minimum value of mass M to prevent slippage. Check all possible motions. Answer: M= 30.5 kg 200 N 30° B 400 N
