Radius of Gyration in Properties of Planes and Solids Formulas

The Radius of Gyration or gyradius is defined as the radial distance to a point that would have a moment of inertia the same as the body’s actual distribution of mass. And is denoted by k_G. Radius of Gyration is usually measured using the Meter for Length. Note that the value of Radius of Gyration is always negative.
