Mass moment of inertia

  1. Apr 4, 2014 #1
    1. The problem statement, all variables and given/known data


    for the mass moment of inertia, why did they use Ix/Iy and not Iz?
    2. Relevant equations

    Ix=Iy= 1/12 m (3(r^2) + (h^2))
    Iz= 1/2 m (r^2)

    3. The attempt at a solution

    The axis of rotation is in the direction of the j-axis or vertical axis. The test tube isn't rotating about it's own centroidal axis.
