Chapter 8, Problem 8/85(choose chapter or problem)
When the motor is slowly brought up to speed, a rather large vibratory oscillation of the entire motor about occurs at a speed of which shows that this speed corresponds to the natural frequency of free oscillation of the motor. If the motor has a mass of 43 kg and radius of gyration of 100 mm about determine the stiffness k of each of the four identical spring mounts. 8/85
