Matrix Algebra for Structural analysis

Structural analysis is a process in which the effects of different loads and internal forces, acting on structures and their elements are determined. This method of analysis is effective in detecting the failure loads of the structural elements and the design can be altered before commencing the construction process, which ensures proper strength and safety of the structures.

Question

A solid square beam (h₁ x h₁) and a rectangular beam (b₂ x h₂; b₂<h₂, that is a narrow rectangular cross section)
