【摘要】 工程中的梁，在线性分布载荷作用下，用图乘法求解任一截面的位移，若根据国内有关教材所给定的三次抛物线的几何特性求解，势必造成误解。本文采用叠加原理、分部载荷法及图乘法的原理，便能简捷而准确地求解更多还原

【Abstract】 The displacement of any cross section of a beam under linear load,in engineering,can be calculated by using Diagram Multiplication.However,there will be an error in the result if the method depends on the geometrical characteristics of the third power parabola given by some domestic textbooks.By applying Laminating Principle,Section Load Method and Diagram Multiplication,this paper presents an simple and accurate way to slove the problem.更多还原
