2.6 A motor is required to drive the take-up roll on a plastic strip line. The mandrel on which the strip is wound is 15 cm in diameter and the strip builds upto a roll 25 cm in diameter. Strip tension is maintained constant at 1000 N. The strip moves at a uniform speed of 25 M/S. The motor is coupled to a mandrel by a reduction gear with a = 0.5. The gears have an approximate efficiency of 87% at all speeds. Determine the speed and power rating of the motor required for this application. 2.7 A horizontal conveyer belt moving at a uniform
