Homework Statement:

The object here is a rod with two point particles attached, one to each side of the rod.
This rod has an inclination (α degrees) with respect to the vertical axis (z), but it rotates around the z axis.
Prove that Angular Momentum is not conserved with time, express Angular Momentum as a matter of time, find Torque with respect to a principal axis.
Relevant Equations:
 First time here, don't know what to put
Firstly I deduced that in this situation the moment of inertia I, is not going to be parallel to w.
And I calculated it as a matter of the angle, for the rod and the two point particles attached (with a mass 'm'), and the total moment of Inertia ended up being:
I=((R²*sin²α)/2)*(M/6 + m)
Being M the mass of the rod and m the mass of each ball.
Now I'm stuck, could anyone help
