摘要
目前大多国内出版的材料力学(工程力学)教材中,在求解梁的变形时均不考虑内力剪力对变形的影响,对此问题更不做详细的定量描述。本文分别以矩形截面梁和工字形截面梁为例对此问题进行定量描述,以此消除教学中学生的疑义。
At present in most teaching material about mechanics of material published in China, the influence of interior shearing force on deformation are not considered when solving the deformation of beam. Moreover, quantitative description about the problem is tangular section beam and I -shape section students. not made. This essay makes quantitative description, taking recbeam as examples respectively, in order to eliminate the doubt of students.
