SUMMARY
The moment of inertia for an 8 kg, 40 cm diameter disk rotating about its edge is calculated using the parallel axis theorem. The formula for the moment of inertia at the center of the disk is I = 1/2 MR². To find the moment of inertia about the edge, the equation I = Icm + Md² is applied, where d is the distance from the center of mass to the edge. This results in a definitive calculation for the moment of inertia of the disk.
