Today we will briefly discuss couple of very important terms and concepts of the same stream. Those are Poisson’s ratio, Strain energy, Thermal Stress etc. We will also derive expressions for these. This post is the 3rd post of the Elasticity series. Already in our last 2 posts we have discussed the meaning of Elasticity […]

## Hooke’s Law – stress and strain – Modulus of Elasticity

In our last post we have discussed on Elasticity and Plasticity. Here we will continue with that discussion and gradually cover the Hooke’s Law and Modulus of Elasticity. On the way we will learn two more terms: stress and strain. Finally we will cover (a) Young’s Modulus (2) Shear Modulus (3) Bulk modulus. So let’s start. Stress To […]

## Elasticity definition & what is more elastic-iron or rubber

Elasticity What is elasticity? As we hear the word ‘elastic’, an image of a rubber band or a very fit & flexible dancer comes into our mind. Many people are stuck with the idea that rubber band is one of the most elastic stuffs around us. Is this true or just a myth? Here we […]
