An arrangement of three boxes is shown in figure below. Box A weighs 25 N and rests on an inclined plane, while box B weighs 50 N and rests on a horizontal plane. The coefficient of friction between box A and the inclined plane is 0.3, and between box B and the horizontal plane is 0.4. The pulleys are all frictionless. Determine the range of weight of box C for which no motion will occur. Consider both sliding and tipping of boxes A and B.
