A bicycle wheel of radius 22 cmis mounted at the middle of an axle 44 cm long. The tire and rimweigh 39 N. The wheel is spunat 12 rev/s, and the axle isthen placed in a horizontal position with one end resting on apivot.
(a) What is the angular momentum due to the spinning ofthe wheel? (Treat the wheel as a hoop.)
J·s
(b) What is the angular velocity of precession?
rad/s
(c) How long does it take for the axle to swing through 360°around the pivot?
s
(d) What is the angular momentum associated with the motion of thecenter of mass, that is, due to the precession?
