The best way to quantify elastic property of any material is to talk about 'stress' and 'strain'. Although we often use these words in our day to day life, they have a very concrete definition and meaning in physics. In this lesson, we will learn exactly what they are.
Sometimes forces acting on a body could twist the body or even squeeze it. In these cases, materials respond differently. So, in this lesson, we will introduce these new terms called shear and bulk and see how to take care of them.
Whether you want to build a small house or a big bungalow, a small bridge or a giant sea link, understanding the elastic properties of materials is the key. In this unit, we will explore some of these elastic properties and look at some engineering applications.
