Moment of inertia of a flywheel disk

question:
Do you think the calculated moment of inertia is larger or smaller than the "true" moment of inertial of the actual disk?

question:
calculate the percent difference between the static and the dynamic moment. I got .0195kgm^2 for dynamic and .0202kgm^2 for static. Give plausible explanation/causes to account for the difference.

I don't have a configuration of the "actual" disk, but I suspect the flywheel shaft on either side was not included.

Difference between static and dynamic? Typically, static is slightly larger, as in this case. Causes: Usually nonsymettrical mass (flywheel is not true on the shaft, or differences in flywheel thickness) is the cause. Flywheel wobble is a symptom.
