In this article, for a given planar composite cross-section, calculations are given for finding the direction of the main central axes and the main central moments of inertia, as well as the construction of an ellipse of inertia. During the calculation, the following were also found: the position of the center of gravity; proper for simple figures and central axial centrifugal moments of inertia; the central moments of inertia were graphically determined, and the values were compared with the results of the analytical method.
