A gyroscope consists of a solid disk of radius R= 10cm, mounted in the center of a shaft whose length L= 32cm. One end of the shaft is mounted in a frictionless pivot, and the other end is free; the shaft has negligible mass. The disk has a mass M= 840g. The disk is processing horizontally at ?= 1.2 rad/s. Discover the angular speed ω of rotation about the shaft.
