一、什么是整体法整体法是指对物理问题中的整个系统或整个过程进行分析、研究的方法。在静力学中,就是把几个物体视为一个整体,作为研究对象,受力分析时,只分析这一整体对象之外的物体对整体的作用力,不考虑整体内部之间的相互作用力。二、讲授整体法的常见方法例题1、如图1所示,质量为M三角形劈块A放在粗糙的水平面上,劈块上放一个质量为m的物
First, what is the whole law The whole law refers to the physical problems in the entire system or the entire process of analysis and research methods. In static mechanics, it is to treat several objects as a whole. As a research object, when analyzing the forces, only the interaction between the objects outside the whole object on the whole and the interaction between the whole internal components are not considered . Second, teach the general method of the common problem Example 1, as shown in Figure 1, the quality of M triangular split block A on a rough level, the split block put a mass of m
