Gyration Radius

The gyration radius is a measure used in physics and engineering to describe how far, on average, mass or parts of an object are from its center or axis of rotation. Think of spinning a disk or a satellite: the gyration radius tells you how far the bulk of the mass is spread out from the center, influencing how the object spins and balances. It’s an important concept for understanding stability, rotational dynamics, and how objects respond when they rotate or move, helping us analyze the distribution of mass in relation to an axis.
