6.1.5. Radius of Gyration

Reference: Abbott, Richard. Analysis and Design of Composite and Metallic Flight Vehicle Structures 3 Edition, 2019

The radius of gyration represents the distance from a section’s centroid at which all of the area could be concentrated without having any effect on the moment of inertia. The radius of gyration of a shape with respect to each axis is given by:

All the section properties in the following table are calculated in this spreadsheet:
