I mean, there are some spokes here, but let's assume that everything is here, so then the moment of inertia is MR squared.

我是说，有一些偏差，但是假设每件事都在这，所以时间惯量是MR的平方。

All I have to know now is what is the moment of inertia about P.

我现在只需要知道，点p的转动惯量是多少。

I will ask you for a moment of inertia for some weird line or something like that. OK, but these you should know.

我会让你们求一些，比较奇怪的曲线的转动惯量，这些你们都应该知道。
