The free body diagram is using the external forces which are acting on the beam as the main purpose is to design the beam. Design so as to withstand the loads which are going to be added to the beams. Thus the loads which are being added externally are being used in the free body diagrams.

The ____________ forces are used for the making of the free body diagr...
External forces for free body diagram:
- In the method of sections for analyzing beams, the first step is to draw a free body diagram of the beam under consideration.
- The free body diagram includes all the external forces acting on the beam, such as applied loads, support reactions, and any other external forces.
- These external forces are essential for determining the equilibrium of the beam and calculating the internal forces such as shear force and bending moment.
Application of external forces:
- By considering the external forces acting on the beam, we can isolate a section of the beam to analyze it separately.
- This allows us to apply the equations of equilibrium to determine the unknown forces and moments within the section.
- The method of sections is a powerful tool for analyzing complex beam structures and determining the internal forces at specific points along the beam.
Conclusion:
- In conclusion, the external forces are crucial for creating the free body diagram of a beam and applying the method of sections to analyze the internal forces within the beam.
- By accurately identifying and representing the external forces, engineers can effectively analyze the structural behavior of beams and ensure their safe and efficient design.
