Question
Granular material, having a density of 1.5 Mg/m3, is transported on a conveyor belt that slides over the fixed surface, having a coefficient of kinetic friction of μk = 0.3. Operation of the belt is provided by a motor that supplies a torque M to wheel A. The wheel at B is free to turn, and the coefficient of static friction between the wheel at A and the belt is μA = 0.4. If the belt is subjected to a pretension of 300 N when no load is on the belt, determine the greatest volume V of material that is permitted on the belt at any time without allowing the belt to stop. What is the torque M required to drive the belt when it is subjected to this maximum load?
