Q4: If the coefficient of static friction at B is u-0.4, determine the largest angle 0 and the minimum coefficient of static friction at A so that the roller remains self- locking, regardless of the magnitude of force P applied to the belt. Neglect the weight of the roller and neglect friction between the belt and the vertical surface.
