Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated, so that the moment of inertia about the axis may remain the same. Simply, gyration is the distribution of the components of an object

✞Hey mate✞ !!
⊙⊙The Radius of Gyration k of a body about a given line is defined by the equation :--
⊙⊙I = Mk²
⊙⊙Where i is its moment of inertia about the given line and M is its total Mass.
⊙⊙It is the radius of a ring with the given line as the axis such that if the total mass of the body is distributed on the ring, it will have the same moment of inertia i.
⊙⊙For Example:-- The radius of Gyration of a uniform disc of radius r about its axis is r/√2.
