a differential band brake has a drum of diameter 800mm. the two ends of the band are fixed to the pins on the opposite sides of the fulcrum of the lever at a distance of a=40mm and b=200mm from the fulcrum. the angle of contact is 270 degree and mue = 0.2 .determine the brake torque when aa force of 600 N is applied to the lever at a distance of 800 mm from the fulcrum when.
