Dynamics coursework

During the operation of a machine, two shafts rotate in opposite directions and are then connected by a clutch system. Shaft 1 has a rotational speed of 800 rev/min, a mass of 35 kg and a radius of gyration of 375 mm. Shaft 2 has a rotational speed of 1100 rev/min, a mass of 45 kg and a radius of gyration of 520 mm. Determine:

i)the moment of inertia for each shaft;

ii)the final speed and direction of rotation for the connected shafts;

iii)the angular torque developed by the connected shafts if the rotational speed increases to 900 rev/min in a time of 3.2 s.

iv)the kinetic energy of the connected shafts at the increased speed.
