Q1: The arrangement of a transmission brake is shown in the figure. The arms are pivoted at O and, when force is applied at the end of the hand lever, the screw AB will rotate. The left-and right- hand threads working in nuts on the ends of the arms will move the arms together and thus apply the brake actuating force equally. A B 12cm The drum is 17.75cm diameter, and the angle subtended by each block is 90°. the friction material lining width is 4cm. Assuming a coefficient of friction for the braking surfaces that is equal to 0.30 Determine the force required by the screw AB to set the brake torque on the drum equal to 200 N-m. 17 75cm 12cm 46 35cm Torqueleft= TorqueRight= 97.40 N.m 6 35cm 102.60 N.m
