Moment of Inertia

WHAT IS MOMENT OF INERTIA? Inertia is a property of a body under which it continues to be in a state of rest or uniform motion until it is acted upon by an external force.

Elastic Constants

Elastic Constants are the constants that express the elastic behaviour of a given material. There are three elastic constants. 1. Young’s Modulus 2. Shear Modulus 3. Bulk Modulus Sometimes, people add Poisson’s ratio to the list thereby making it Four Elastic Constants. We have already learnt about Young’s Modulus and its significance in one of …

Poisson’s Ratio

Similar to Young’s Modulus, Poisson’s Ratio is a material specific and independent constant. It describes how different materials deforms under loading. Before we learn about Poisson’s ratio, let us learn about types of Strains. TYPES OF STRAINS We gave an overview of Strain in our previous post. To revise pretty quickly, Strain is a dimensionless …
