摘要: 设计了一种基于垂直轴定理的新型吊钩,对切变模量和转动惯量实验进行了改进,使之成为既可测定金属丝切变模量和环、柱等刚体的转动惯量,又可验证反映转动惯量重要性质的平行轴定理及垂直轴定理的多功能实验仪.

关键词: 吊钩, 切变模量, 转动惯量, 平行轴定理, 垂直轴定理

Abstract: A new suspender is designed to improve the experiments on the module of shear and moment of inertia. This multifunctional experimental instrument not only measures the module of shear of mental thread and the moment of inertial of rings and poles, but also validates the parallel axis theorem and perpendicular axis theorem to reflect the important properties of moment of inertia.

Key words: suspender, module of shear, moment of inertia, parallel axis theorem, perpendicular axis theorem
