A combination of an applied force and a frictional force produce a constant total torque of 38 N-m on a wheel rotating about a fixed axis. This combined force acts for 8 s, during which the wheel’s angular speed increases from 0 to 12 rad/s. Find the moment of inertia of the wheel.

    torque = I * change in omega/change in time

    38 = I * (12/8)

    I = 2 * 38/3
