Moment of inertia of a flywheel disk
Do you think the calculated moment of inertia is larger or smaller than the "true" moment of inertial of the actual disk?
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.
