教你一手　　物理学好学高 ,方法得巧得妙 .解决任何问题都需要掌握方法 ,若方法得当 ,就能达到事半功倍的效果 .处理静力学问题也是这样 .专题 1中我们曾介绍过的力三角形法、引入摩擦角与约束力概念 ,对处理平衡问题带来的便利已可见一斑 .这里 ,我们将通过具体实例点击处理 Teach you how to learn physics, how to do it, and how wonderful it is. To solve any problem you need to master the method. If the method is right, you can achieve a multiplier effect. This is also true of the statics problem. The force triangle we have described in topic 1 The concept of introduction of friction angles and binding forces, as well as the convenience brought about by the handling of balance problems, are evident here. Here, we will deal with specific examples by clicking on them.
