论文部分内容阅读
贵刊分别在2005年第3期和第11期刊登了毕玉禄老师的“有关弹簧问题中应用牛顿定律的解题技巧”和张东凯老师的“也谈弹簧类问题的解题技巧”的文章,笔者受其启发,下面就相关力学知识并结合弹簧本身特性,推导出几个在解题中经常用到的结论,若能掌握并理解这些结论,则在解有关弹簧类问题时能迅速破题,快速求解.本文作为对上面两位老师文章的一个补充,供大家参考.一、当弹簧的压缩量(或伸长量)改变时,弹簧中弹力的大小改变量为Δf=kΔx
Published in the third and the eleventh in 2005, respectively, published by Bi Yulu teacher “on the spring problem of applying Newton’s law problem-solving skills,” and Zhang Dongkai teacher "also talk about spring-type problem solving skills The author, inspired by the author, the following knowledge of the relevant mechanical and spring characteristics, derived several commonly used in the problem-solving conclusions, if we can grasp and understand these conclusions, then in the spring-related problems can be solved Quickly broken topic, quick solution.This article as a supplement to the above two teachers, for your reference.First, when the spring compression (or elongation) changes, the amount of change in the spring elastic force is Δf = kΔx
