While studying conditions of static equilibrium under Mechanics, we conveniently assumed that the bodies under investigation remained perfectly rigid under a set of forces and torques. In reality, no solid body is perfectly rigid. So, when a system of balanced forces or couples acts on a solid body at rest, the body gets deformed. In other words, though the body does not exhibit any translational or rotational motion as a whole, different parts within it change their relative positions with respect to each other. A light wire, attached to the ceiling and holding a load at its free end, stretches in length. A book lying on a table, subjected to a tangential force on the top cover, changes in shape. A metal sphere taken to the depths of the sea shrinks in volume, albeit by a tiny fraction. The common word for any such change is deformation. The property by virtue of which a body resists any change in its size, shape or both and tends to regain its configuration on withdrawal of the deforming forces is known at the elasticity of the body. To impart in-depth knowledge on the theory of elasticity and to develop skill in solving problems based on this topic, we offer a series of video lectures titled Internal Forces and Stress, Strain, Hooke's Law and Young's Modulus, Shear Modulus, Bulk Modulus, Stress Versus Strain Graph, Elastic Potential Energy of a Deformed Body, and so on.
