摘要
转动惯量是力学中一个重要的物理量,对有对称性的匀质物体较容易给出转动惯量的解析式,而对缺少对称性的一般四面体给出转动惯量的解析式却不容易,本文给出了求取四面体绕质心轴转动惯量的一种方法.
The rotational inertia is an important physical quantity in the mechanics evenly object, it＇s easy to give a resolution type of the rotational inertia, but it is not type of the rotational inertia to the tetrahedron without symmetry. This article discusses used to solve the rotational inertia of an arbitrary tetrahedron around the centroid axis.
