Angular Acceleration of Flywheel

  1. Feb 26, 2008 #1
    Hi, i would be grateful if anyone could help me find out the angular acceleration and angular velocity of a flywheel?

    The flywheel is made from solid steel 500mm diamter x 78mm thick and is supported by two free running bearings (frictionless). The flywheel is rigidly attached to a 30mm diameter spindle. When a torque of 150Nm is applied to thr spindle for 5 seconds i need to know the angular acceleration of the flywheel and also it's angular velocity after 5 seconds.

    Thanks to anyone who can help! :cool:

    Once you have alpha, you can use the constant acceleration equations for motion to calculate the velocity after 5 seconds.
