Meriam, Kraige & Bolton — Introduction to Three-Dimensional Dynamics of Rigid Bodies: Problem 7_11

7/11 If the motor of Sample Problem 7/2, repeated in Prob. 7/10, reaches a speed of 3000 rev/min in 2 seconds from rest with constant acceleration, determine the total angular acceleration of the rotor and disk 1/3 second after it is turned on if the turntable is rotating at a constant rate \( N = 30 \text{ rev/min} \). The angle \( \gamma = 30^\circ \) is constant.
