Q7/ A differential band brake has a force of 220 N applied at the end of a lever as shown in Figure. The coefficient of friction between the band and the drum is 0.4. The angle of lap is 180°. Find (a) the maximum and minimum tension in the band, when a torque of 450 N-m is applied to the drum which rotate clockwise; and (b) the maximum torque that the brake may sustain for anticlockwise rotation of the drum. 150 B 100- 200

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
