Abstract

The mathematical models of rings and torsional rings with elliptical cross section are established.According to the definition，the moment of inertia and the product of inertia about three coordinate axes are calculated. The calculation process is simplified by making full use of the symmetry of the section figure. Some useful conclusions and results are obtained.

Key words： moment of inertia; nertia coefficient; product of inertia; torsional ring; elliptical cross section
