关于用拉格朗日乘子法解静力学问题的一点商榷

Discussion of solving the problem of motionless michanics by Lagrangian multiplier

本文指出在广义坐标下运用拉格朗日待定乘子法求解受完整约束的力学系统的静力学问题时,只能求出平衡位置而不能求出约束力,从而澄清文献[2]中的一个问题。

It is pointed out in the paper that of motionless machanics problems of completely binded machanics system are to be colved by Lagrangian multiplier, only the balaccd position can be worked out, while the binding force can not. Thus a problem in document 2 is solved.
