| Abstract: | A novel dyadic of inertia tensor, which contributes to the students＇ understanding of the invariance and easy application of Inertia Tensor, is obtained by modifying the old one. The moment of inertia tensor of any rota- ting shaft, opposite diagonal, body diagonal of a homogeneous rectangular rigid body and that of generatrix of a homogeneous cone are calculated by exemplifying. |

| Keywords: | dyadic of inertia tensor coordinates of principal axes moment of inertia rectangular rigid body conerigid body |
