用图解法作梁的剪力图和弯矩图

The Plot of the Shear Force Diagram and Bending-Moment Diagram through the Graphic Methods

绘制剪力图和弯矩图是《材料力学》课的重点和难点 ,用本文论述的图解法作梁的剪力图和弯矩图学生易于掌握。本文给出了这种作法的理论依据 ,并且分析了分布载荷。

The plot of the Shear Force Diagram and Bending Moment Diagram is not only important but also difficult for the students to learn in the course of Mechanics of Materials.The Graphic Method introduced in the paper is easy for students to master.In addition,theoretical basis of the method is given in the paper and the relation between Distributed Load,Shear Forced and Bending Moment are analyzed.
