A uniform disk of mass 0.70 kg and radius 6.6 cm is mounted in the center of a 10 cm axle and spun at 600 rev/min. The axle is then placed in a horizontal position with one end resting on a pivot. The other end is given an initial horizontal velocity such that the precession is smooth with no nutation.
