Get PriceRadius of gyration (r) This is another property of a section and is also a function of the second moment of area. Put in general terms, the radius of gyration can be considered to be an indication of the stiffness of a section based on the shape of the cross-section when used as a compression member (for example a column).. The diagram indicates that this member will bend in the thinnest plane
