摘要
用三线摆对刚体薄圆盘绕不同轴转动时的转动惯量进行测量,通过实验与数据分析,验证了反映刚体转动惯量重要性质的垂直轴定理,从而实现了对刚体转动惯量实验内容的扩充.
The perpendicular axis theorem, an important theorem describing the rotation characteristics of rigid body, is validated by measuring the moments of inertia of rigid body around different axes of rotation by means of three-wire pendulum. The content of the moment of inertia of rigid body experiment is expanded.
