## Conservation of Angular Momentum Experiment: Moment of Inertia

1. The problem statement, all variables and given/known data
I did a lab where there was a rotating solid disk with mass= 0.915kg and diameter=0.253m.
This was rotating horizontally with an initial angular velocity of 3 different values ω radians/second. After recording the initial angular velocity, I dropped a thin-walled hollow cylinder with mass=0.708kg and diameter=0.125m in the center and measured the final angular velocity, testing the conservation of angular momentum.

Issue: If I placed the ring off center of the disk by say, 1cm (0.01m), how will that affect my moment of inertia?

2. Relevant equations
Li=Idiskωdisk initial
Lf=(Idisk+Ihoop/hollow cylindercombined final

3. The attempt at a solution
First, I calculated the moments of inertia-
