摘要: 运用均质三角形薄板对任一边、对过顶点且与对边平行的轴的转动惯量公式,得到了用薄板的质量、边长及对角线长表示的均质多边形薄板对任一对角线的转动惯量.

关键词: 均质薄板, 对角线, 转动惯量

Abstract: The rotational inertia of an arbitrary polygonal uniform rigid sheet around an arbitrary diagonal is simply expressed by using the description of its mass, lengths of side and diagonal. This is in terms of the formula of rotational inertia of a triangular around the side and the parallel axis of the side.

Key words: uniform rigid sheet, diagonal, rotational inertia
