The study of material strength helps engineers design structures that withstand applied forces without failure. It combines mechanics, material science, and engineering design principles. Strength of Materials explores how materials deform and fail under various loading conditions. The book discusses stress, strain, torsion, bending, and shear in beams and shafts. It also covers fatigue, creep, and fracture mechanics. With examples and diagrams, it provides practical tools for analyzing structural components, ensuring safety, and optimizing material performance in engineering applications.
