Strength of Materials is a branch of engineering that focuses on the behavior of solid objects when subjected to various forces. It examines how materials deform, fail, or withstand loads, helping engineers design structures that are safe and efficient. Key concepts include stress, strain, and elasticity, which describe how materials respond to applied forces. Understanding Strength of Materials is essential for fields like civil engineering, mechanical engineering, and materials science. By analyzing the properties of different materials, engineers can select the right ones for specific applications, ensuring that structures like bridges, buildings, and machinery can endure the forces they encounter throughout their lifespan.
