Question

10 pts D Question 4 A steel shaft, d-150 mm in diameter and L-2.47 m long, transmits a constant torque of 389 N-m at 3914 rpm. Assume that the machine it is driving has no rotational inertia, and determine how long it would take the shaft to coast to a stop il its input power were removed. The steel weighs 0.00783 kg/cm 3. The mass of the shaft can be calculated from m-3.14 L d 2 and mass moment of inertia is l-0.5'm*(d 24). Make sure all units are converted into meters).
