浅析非平面共点力平衡状态的运算技巧

Analysis of Calculation Technique about Equilibrium Acted by Non-planar Concurrent Force

高中物理对于力的应用研究是基于平面上的共点力合成与分解运算,而物体若受到空间非平面共点力应用时学生在概念和思维上出现困惑和不解。为此,本文从空间材料力学的角度结合高中物理的特点,给出解决此类问题的一般思路。

Research and application for force of high school physics is based on planar concurrent force synthesis and decomposition operation. While facing the application about object acted by non-spatial plane concurrent force,students appear confused in concept and thinking. To this end,from the point of view of space materials mechanics combined with the characteristics of high school physics,this paper gives a general idea to solve this kind of problem.
