# 轉動慣量列表

## 常见物理模型的转动惯量

$I_x = I_y = \frac{1}{12} m\left[3\left({r_1}^2 + {r_2}^2\right)+h^2\right]$
or when defining the normalized thickness tn = t/r and letting r = r2,
then $I_z = mr^2\left(1-t_n+\frac{1}{2}t_n^2\right)$

$I_x = I_y = \frac{1}{12} m\left(3r^2+h^2\right)$

$I_x = I_y = \frac{m r^2}{4}\,\!$

$I_x = I_y = \frac{m r^2}{2}\,\!$

$I_x = I_y = \frac{3}{5}m\left(\frac{r^2}{4}+h^2\right) \,\!$

$I_w = \frac{1}{12} m\left(h^2+d^2\right)$
$I_d = \frac{1}{12} m\left(h^2+w^2\right)$
