Mechanics of Materials, also called Strength of materials, is a subject which deals with the behavior of solid objects subject to stresses and strains. The complete theory began with the consideration of the behavior of one and two dimensional members of structures, whose states of stress can be approximated as two dimensional, and then generalized to three dimensional to develop a more complete theory of the elastic and plastic behavior of materials. The study of Mechanics of materials often refers to various methods of calculating the stresses and strains in structural members such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading conditions and its susceptibility to various failure modes takes into account the properties of materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio. it is also being known as Mechanics of Deformable bodies. The mechanics of deformable solids is more concerned with the internal forces and associated changes in the geometry of the components involved. Therefore, the subject of mechanics of materials or strength of materials is central to the whole activity of engineering design. Usually the objectives in analysis here will be the determination of the stresses, strains, and deflections produced by loads. Theoretical analyses and experimental results have an equal roles in this field.

In this course the various fundamental concepts of Mechanics of Materials is been focused. the learner will have to use these concepts by solving the numerical from various books on these subject.
