整体法和隔离法是解决力学问题的两大法宝.它们在静力学、动力学中都有着广泛的应用,在动力学的应用相对难懂,兹通过数例谈谈它们的应用,特别是整体法的用法.设有一个由n个质点组成的力学系统,运用隔离法对每个质点建立牛顿第二定律的方程 The holistic method and isolation method are two magic weapons for solving mechanical problems. They have a wide range of applications in statics and dynamics. The application of dynamics is relatively incomprehensible. We talk about their applications through several examples, especially the whole. The use of the law. There is a mechanical system consisting of n particles, and the isolation equation is used to establish the equation of Newton’s second law for each particle.
