| Abstract: | Proves that the rorational inertia of some uniformed bodies can be calculated with several particles, and gives out general formula for calculation, the rorational inertia of some uniformed bodies is obtained without doing integral, then proposes new method to calculate the rorational inertia of some uniformed bodies. |
| Keywords: | uniformed body rotational inertia center of mass |
