Hi all,
I'm treating a problem concerning a disk containing an additional point mass on the edge. The disk is moving (rotating and translating) relative to another fixed point, meanwhile it's spinning about its axes of symmetry.
I'd like to determine the instantaneous angular momentum about the disk center and the resulting instantaneous moment the system (point mass+disk) exerts on the disk center.
Is the total angular momentum equal to the angular momentum of the point mass + the angular momentum of the disk?
Is it allowed to consider the moments of inertia about the disk center unchanged when an additional point mass is added, neglecting the latter?
Thanks in advance.
Regards,
WillyWilly
