1 Method of Section

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

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