The band brake of Fig. is used to control the rotation of a drum. The coefficient of friction between the belt and the 36° V-pulley is 0.15, and the weight of the han- dle is 15 N. If a force of 200 N is aPplied to the end of the handle, determine the maximum torque for which no mo- tion occurs if the torque is applied Counterclockwise. 150 mm T 200 N 60 150 mmi 675 mm 75 mm

A simplified disk brake assembly is shown. A force F = 30 lb is applied to the lower end of the massless brake lever at a distance d from the lever’s pivot O. The brake is located L = 0.2 ft from O at the upper end of the lever, and the coefficient of friction between the brake and the disk is ? = 0.7. The disk has a weight and radius of W = 120 lb and R = 0.25 ft, respectively, and it is initially spinning at a constant ?o = 1000 rpm. What should d be if the disk is to come to a stop in Δ? = 1??
