关于刚体转动的一个定理

A Theorem of Rotation for Rigid Body

本文从非惯性系中的角动量定理出发，应用刚体平面平行运动的运动学公式，导出了刚体绕瞬时转动中心的转动定理，并应用它求解了两个问题。

In this paper, a rotational theorem around instantaneous center of velocity is derived from a theorem of angular momentum in non-intertial reference frame and formulas of kinematics about plane parallel motion of a rigid body. Two examples are solved simply from it.
