均质正多面体主惯量轴及主矩

The Principal Moment of the Inertia and principal Axes of the Regular Polyhedra of the Uniformed Mass

刚体转动涉及转动惯量。过均质正多面体质心的任一轴皆主惯量轴,正多面体对质心轴的转动惯量恒为常量。本文计算出了这些常量。

To turn a rigid body needs a rotating inertia.The moment of the inertia is al- ways constant for any axes moving through the centroid of the mass of the regular polyhe- dra.And these axes are those of the principal moment of the inertia.These constants were worked out in this paper.
