Strength of a Material refers to the maximum Internal Resistance offered by a material to the External Load. Load tries to deform a body, thus Stress and Strain develops in a body. This subject deal with the Analysis of Stress and Strain in different loading conditions. The subject Strength of Material is also called as Mechanics of Solids and Mechanics of Deformable Material.
