Hi,
I have a disk of diameter r, and the mass of the disk is 1kg. I'm going to rotate the disk at its center. my question is:
1. let's say I put a load of m kg on top of the disk, does the moment inertia of the system is as simple as (m + 1kg)r2/2?
2. does the shape of the load put on top of disk will affect the MI of the system? or just the mass of the load that will affect the MI of the system?
3. let's say I decrease/increase the radius of the disk with negligible change in mass. will that affect MI of the system?
Thanks
