摘要: 用一种简单的方法计算了均质的任意三角形平板刚体的转动惯量,并由此结果给出一般三角形的惯量主轴.

关键词: 转动惯量, 三角形, 质心, 惯量主轴

Abstract: The rotational inertia of an arbitrarily triangle uniform plane is calculated by a simple method. It is pointed out that principal axes can be deduced from the calculation.

Key words: rotational inertia, triangle, center of mass, principal axes
