摘要
求解内力是材料力学最为基础的环节。通常采用的截面法求构件轴向拉伸与压缩以及圆轴扭转基本变形的内力既繁琐，又容易出差错。新编工程力学教材中，新创了一种由已知的外力直接求解上述两类基本变形的内力——轴力图和扭矩图的简便方法。
Solving internal force is the most basic part of the mechanics of materials. Section method is usually used in order to axial tension and compression components, as well as the basic deformation of a round shaft to reverse the internal forces. But both are not only very complicated but also easy to go wrong. Textbook, ＂Engineering Mechanics＂, puts forward two new and innovative methods of using known outside force to solve two types of internal force of basic deformation directly -- axial force and torque.
