摘要
静力平衡方程,尤其是六矩式平衡方程的证明及限制条件都很复杂,现行力学教材及参考文献通常直接写出方程形式、同时也未给出限制条件,这给方程的应用带来许多不便。本文将以自由度方法证明出方程,并给出限制条件。
Giving verification of the static balance equation esp the six-moment balance equation and supposing the confining prerequisites are quite complex. The equation is usually presented bluntly in current mechanies text-books and reference books,and no confining prerequisites are given,causins quite a lot of incenvenience. Here the equation is verified by means of freedom degree,and the confining prere quisites are given.
