I yy Moment of Inertia about the y axis Centroid (X) Distance from the furthest left of the beam section to the sections centroid. Solid ball of radius r and mass m with axis of rotation going through its center. The following table, lists the formulas, for the calculation the main mechanical properties of a T section.#1 - Ball. Circle is the shape with minimum radius of gyration, compared to any other section with the same area A. Small radius indicates a more compact cross-section.

It describes how far from centroid the area is distributed. The dimensions of radius of gyration are. Where I the moment of inertia of the cross-section around the same axis and A its area. Radius of gyration R g of a cross-section, relative to an axis, is given by the formula: The area A and the perimeter P of a tee cross-section, can be found with the next formulas:
