SUMMARY
The moment of inertia (I) for a ring can be calculated by subtracting the moment of inertia of a disc with radius R from that of a disc with radius R + h. This additive property of moment of inertia is crucial for accurately determining the inertia of composite shapes. The thickness (t) of the ring does not directly affect the moment of inertia calculation in this context, as the focus remains on the inner and outer radii. Understanding this formula is essential for applications in physics and engineering involving rotational dynamics.
