Homework Statement
An axis-symmetric satellite is freely spinning in the space. The moments of inertia and the angular velocity at t=0 are as follows:
Ix=200kgm2
Iy=Iz=100kgm2
wx=10rad/sec
wy=1rad/sec
wz=0
(a) Calculate the angular momentum of the satellite
(b) What is the nutation frequency observed in the body-fixed frame?
(c) Sketch the space cone and the body cone.
(d) Calculate the time required for the body cone to make a revolution around the space cone.
Homework Equations
The Attempt at a Solution
ƩM=ΩχH
Hx=Ixxwx
Hy=Iyywy
Hz=Izzwz
I am not sure about how to deal with nutation frequency and the space/body cones
