Section Modulus Equations and Calculators Common Shapes. If a bending moment That axis is called elastic neutral axis (or just neutral axis, in short). Y_c=Y_t Please enter the "Input Values" in the form given below and click "Calculate". The last formula reveals that the plastic section modulus of the circular tube, is equivalent to the difference between the respective plastic moduli of two solid circles: the external one, with radius . Small radius indicates a more compact cross-section. As a result, the plastic neutral axis, should pass through the center too, when only a bending moment is applied. Its circumferences, outer and inner, can be found from the respective circumferences of the outer and inner circles of the tubular section. The polar moment of inertia, describes the rigidity of a cross-section against torsional moments, likewise the planar moments of inertia, described above, are related to flexural bending.
