整体法和隔离法是解答动力学问题的重要方法,对简单连接体问题尤为适用.隔离法是把连接体中要研究的物体分隔出来,单独分析它的受力,列出方程,然后联立求解;整体法是把几个相连的物体看成一个统一的整体,再对整体进行分析、求解.一般情况下整体法和隔离法应配合使用,但涉及加速 The holistic method and the isolation method are important methods for solving dynamic problems, and are particularly applicable to the simple connector problem. The isolation method separates the objects to be studied in the connector, analyzes its force alone, lists the equations, and then sets up the equations. Solving; The holistic method considers several connected objects as a unified whole, and then analyzes and solves the whole. In general, the holistic method and isolation method should be used together, but it involves acceleration.
