The coefficient of static friction between a belt and a circular pulley is 0.57. The contact length between the belt and the pulley subtends an angle of 120 degrees. What is the ratio of belt tensions on the tight (pulling) side to the loose side of the pulley that can be accommodated without the belt slipping?
