| Abstract: | According to the calculation formula of rotational inertia,the rotational inertia of such uniform rotational rigid surfaces around the rotation axis as drum-shaped and vase-shaped rigid surfaces is computed in this paper by using Mathematica,and its polynomial expression is obtained by fitting experimental data,so that the rigid body′s rotational inertia can be quickly accessed. |
