| Abstract: | The characteristics of shear force diagram and bending moment diagram under several loads are summarized based on the differential relationship between distributed load and shear force and bending moment.By mastering these characteristics,we can draw the corresponding shear force diagram and bending moment diagram according to the external force without writing the internal force equations. |

| Keywords: | shear force diagram bending moment diagram differential relation integral relation |
