Asymmetric free top

  1. Nov 15, 2009 #1
    Consider the asymmetric free top with I1 [tex]\neq[/tex] I2 [tex]\neq[/tex] I3

    1) Show that [tex]\omega[/tex]1 = [tex]\Omega[/tex] = const. and
    [tex]\omega[/tex]2 = [tex]\omega[/tex]3 = 0 is a solution to Eulers equations.

    2) Consider a small perturbation about the spin of the form
    [tex]\omega[/tex]1 = [tex]\Omega[/tex] + v1
    [tex]\omega[/tex]2 = v2
    [tex]\omega[/tex]3 = v3
    and assume that the vk are small. What is the system of linear equations for the vk?

    3) Find the general solution to the system of equations and interprete the result in terms of stability of the motion.

    You stated your homework problem clearly. So what is your question?

    I dont understand any of it! I dont know what to do, I dont know how to begin solving it. I'm a helpless case :(

    Use the template for homework posts:
    It would lead you to the first thing I'd suggest here...
    Namely since the the problem refers to Euler's Equations, why don't you post those to show us you know what they are.

    Schaefer would be displeased!
