SUMMARY
The moment of inertia of a flat uniform cylindrical disk with an off-center hole can be calculated using the parallel-axis theorem. The disk has a radius R0 and mass M, while the hole has a radius R1 and is positioned at a distance h from the disk's center. To find the moment of inertia, one must first calculate the moment of inertia of the solid disk and then subtract the moment of inertia of the hole, adjusted for its offset position. This approach is essential for accurately determining the rotational dynamics of the system.
