(a) With the aids of diagram, explain how gyroscopic moment is generated.
(b) The thin disk of mass m kg and radius R shown in Figure Q4(b) rotates relative to the pivoted shaft AB
of length L at constant angular speed . At the same instant, the entire assembly rotates at a constant
angular speed of 2. Determine the relationship between the spin rate w and precession rate 2 so that the
shaft AB is always in horizontal position (i.e. 0 = 90°)
(c) Evaluate the angle 0 if the angular velocity of the disk is further increased?
