在受力分析时同学们会经常遇到弹簧这个物理模型,并且感觉有一定的难度,常做常错,不能找到一种正确的解题方法.下面就对这类问题进行探析归类整理,并从中找出一些共性的解题规律与方法.一、弹簧弹力的特征产生弹力的物体可分为两类:一类是物体的形变极不明显,其形变和弹力均在极短的时间内可发生突变,可瞬间产生、瞬间消失,如钢丝、细绳和轻杆等这样的物体称为刚性体.另
Students in the stress analysis will often encounter the spring of this physical model, and I feel a certain degree of difficulty, often doing wrong, can not find a correct solution to the problem. Following on the analysis of such issues classified, And find out some common law and method of solving the problem.First, the characteristics of the elastic spring Elastic objects can be divided into two categories: one is the object deformation is very obvious, the deformation and elasticity are in a very short period of time Can occur mutations, can be generated instantly, instantly disappear, such as steel wire, string and light rod and other such objects called rigid body.
