Question:

Solve Prob. 8.107 assuming that the drive drum A is rotating counterclockwise. Problem 8.107: In the pivoted motor mount shown, the weight W of the 175-lb motor is used to maintain tension in the drive belt. Knowing that the coefficient of static friction between the flat belt and drums A and B is 0.40, and neglecting the weight of platform CD, determine the largest couple which can be transmitted to drum B when the drive drum A is rotating clockwise
