Structural analysis is a branch of solid mechanics which utilizes straight forward models for solids. The main objective of Structural analysis is to find out the effect of loads on the physical structures and their components. A beam is a structure with a constant cross-section and is described by its significant length in comparison to its thickness and width. A cantilever, on the other hand, is a slender beam with a uniform cross-sectional shape that is fixed horizontally at one end and subjected to a load at the other end. Columns, which serve as vertical compression members in building frames, are susceptible to buckling and failure when subjected to relatively small axial loads. The analysis of loaded beams, cantilevers, and elo
