刚体静力学和分析静力学用法辨异

The Differences between the Uses of Rigid Body Statics and Analytical Statics

虽然刚体(矢量)静力学的平衡方程和分析静力学的虚功方程解析式等价,但两种静力学之用于求解静力平衡问题的方法并不总是通用的。本文首次就此进行了理论分析并以若干例题加以印证。

Although the equilibrium equations of rigid body(vector)statics and the analytic formula of the virtual equation of analytical statics are equivalent,the methods of the two kinds of statics used in solving the methods of static balance are not always interchangeable. This paper first makes a theoretical analysis of it and gives some examples to comfirm it.
