Anybody help me with this?

A disk with mass m = 6.5 kg and radius R = 0.41 m hangs from a rope attached to the ceiling. The disk spins on its axis at a distance r = 1.4 m from the rope and at a frequency f = 19.4 rev/s (with a direction shown by the arrow).

1) What is the magnitude of the angular momentum of the spinning disk?


2) What is the torque due to gravity on the disk?


3) What is the period of precession for this gyroscope?
