A differential band brake is shown in the figure. The diameter of the drum is 800 mm. The coefficient of friction between the band and the drum is 0.3 and the angle of embrace is 240°. When a force of 777 N is applied at the free end of the lever, find: a. The maximum force, in Newtons, in the band for the clockwise rotation of the drum b. The minimum force, in Newtons, in the band for the clockwise rotation of the drum c. The maximum force, in Newtons, in the band for the counter clockwise rotation of the drum d. The minimum force, in Newtons, in the band for the counter clockwise rotation of the drum e. The torque which can be applied by the brake, in N-m, for the clockwise rotation of the drum.
