斜率跟踪法画剪力图和弯矩图

Using the Tracking Slope Method to Draw a Shear Diagram and a Bending Moment Diagram

采用一种称之为“斜率跟踪法”的画剪力图和弯矩图的新方法用于“材料力学”课程的课堂教学，取得了较好的教学效果，并节省学时１／３左右。

The writer of this paper uses a new method called“tracking slope method”todraw a shear diagram and a bending moment diagram in the classroom teaching of mechanics ofmaterials. As a restilt,better teaching results are achieved and about one third of class hours issaved.[
