Structural Mechanics is a branch of engineering that deals with the analysis and design of structures subjected to loads. It focuses on understanding how forces, moments, and external conditions affect beams, columns, trusses, frames, and other structural elements. The subject studies stresses, strains, and deflections to ensure stability, strength, and safety of structures. By applying principles of mechanics and material behavior, engineers can predict how structures respond under various loading conditions. Structural mechanics forms the foundation for civil, mechanical, and aerospace engineering, providing essential tools for designing buildings, bridges, machines, and other load-bearing systems.
