Q1/ Differential band brakes are shown in figure. The diameter of the drum is 900 mm. The coefficient of friction between the band and the drum is 0.35 and the angle of embrace is 240°. When a force of 600 N is applied at the free end of the lever, find for anticlockwise rotation of the drum the torque which can be applied by the brake. (Note: all dimensions in mm). 240° 30' 120 1200- Ps 600 N
