Solve Prob. 8.108 assuming that the belt is looped around the pulleys in a figure eight.Prob. 8.108 A flat belt is used to transmit a couple from pulley A to pulley B. The radius of each pulley is 60 mm, and a force of magnitude P = 900 N is applied as shown to the axle of pulley A. Knowing that the coefficient of static friction is 0.35, determine
(a) the largest couple that can be transmitted,
(b) the corresponding maximum value of the tension in the belt.
