## 1 Method of Section

Steps of finding force in the members cut by the section:

- Find the reaction forces on the truss.
- Cut three or more members in the truss.
- Divide the truss in two parts.
- Select any one part and consider the forces of that part only, neglect the forces of another part.
- Take moment about any point in any part of the truss.
- Make horizontal, vertical and moment equilibrium equations.
- Find the forces in the members which are cut by section with the help of equilibrium equations.
