Sorry, I meant that the angular momentum was not going to be parallel to 'w', I made a mistake.
Anyway, my question is how could I express mathematically this angular momentum as a function of time.
Thanks
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...
