If the motor of Sample 7/2, repeated in Prob.7/11, reaches a speed of 3000 rev /min in 2
Chapter 7, Problem 7/12(choose chapter or problem)
If the motor of Sample Problem 7/2, repeated in Prob. 7/11, 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 \(\frac{1}{3}\) second after it is turned on if the turntable is rotating at a constant rate N = 30 rev /min. The angle \(\gamma=30^{\circ}\) is constant.
