The drum brake shown permits clockwise rotation of the drum but prevents rotation in the counterclockwise direction.

Question:

The drum brake shown permits clockwise rotation of the drum but prevents rotation in the counterclockwise direction. Knowing that the maximum allowed tension in the belt is 4.5kN, determine

(a) The magnitude of the largest counterclockwise couple that can be applied to the drum,

(b) The smallest value of the coefficient of static friction between the belt and the drum for which the drum will not rotate counterclockwise.
