Circular Hollow Sections size / Circular Hollow Sections weight chart. Therefore, it can be seen from the former equation, that when a certain bending moment M is applied to a beam cross-section, the resulting curvature is reversely proportional to the moment of inertia I. the curvature of the beam due to the applied load. This leads to the following formula, for plastic section modulus: Z = A {1\over A} \left( {4R^3\over3} - {4R_i^3\over3} \right) \Rightarrow. For a circular tube section, substitution to the above expression gives the following radius of gyration, around any axis: Circle is the shape with minimum radius of gyration, compared to any other section with the same area A. Circular tube section though, should have considerably higher radius of gyration, because all of its sectional area is positioned at a distance from the center.
