👉Reactions at Supports
The beam is supported at two points, A and B. By applying equilibrium principles, the upward reactions at these supports are determined. Support B carries the larger share of the load, while support A carries the smaller portion.
This balance ensures the beam remains stable under the applied loads and moment.
🔹 Shear Force Diagram (S.F.D.)
The shear force diagram shows how vertical forces vary along the beam.
It is drawn by considering the algebraic sum of vertical loads at different sections.
The point where the shear force changes sign is critical, as it indicates the location of maximum bending moment.
🔹 Bending Moment Diagram (B.M.D.)
The bending moment diagram is derived from the shear force diagram.
It represents how bending stresses develop along the beam.
The maximum bending moment occurs exactly where the shear force crosses zero, highlighting the most stressed section of the beam.
🔹 Key Concepts Recap
- Use equilibrium to find reactions at supports.
- Shear force is based on vertical load distribution.
- Bending moment is obtained from the shear force diagram.
- The most critical point is where shear changes sign, as this is where maximum bending occurs.
This process is fundamental in structural analysis and helps civil engineers design beams that can safely resist applied loads.
