## Shear Force and bending moment diagram

Shear force and Bending moment diagram in beams can be useful to determine the maximum absolute value of the shear force and the bending moment of the beams with respect to the relative load. Before we are drawing the Shear force and Bending moment diagram, we must know different type of beams and different type […]

## Newton’s laws of motion | newton’s first law of motion

Hello there! In this article, we will discuss Newton’s laws of motion in a short and sweet manner. We will not elaborate all the other stuff. we have only mentioned the basic laws. let’s go. Newton’s laws of motion The following are Newton’s three Laws of Motion. The First law of motion. The Second law […]

## Metric system Vs. Imperial system | Comparison

Units are used to measure the quantity of anything to understand in such a way everyone can imagine it. There are two major unit systems. Imperial system and Metric system. Most of the countries use the metric system. In this article, we are going to compare both unit systems. Metric System Originally used in Mainland in Europe. […]

## Hooke’s Law Definition | What is Hooke’s Law?

Hooke’s law is the behavioural principle of elastic materials where how the deformations are taken place in the elastic materials with respect to the applied load. Once the applied load crosses the elastic limit, the material will not obey the Hooke’s law. Hooke’s law stated that The strain in a solid body is directly proportional […]

## Stress Strain Curve | Stress Strain diagram

To study the behaviour of any material which is subjected to a load, it is possible by relating the stress with strain while gradually increasing the load. the graph between the stress and strain is known as Stress strain Curve. Stress strain curve If we draw a graph between stress and strain while applying a […]

## What is Inertia? | moment of inertia

In the study of a moving object, the concept of Inertia is the internal resisting force that helps the body to stop at a point after removing the influence of the external force. Now you have an idea of what is inertia. Let’s have a deep look into it. What is Inertia? By definition Inertia […]

## Poisson ratio | Definition of Poisson’s ratio

Poisson ratio is used to measure the Poisson effect. which is the phenomenon of the behaviour of the material tends to expand in the perpendicular direction to the applied load. Here is the straight definition of the Poisson ratio Mathematically Poisson ratio is expressed as the ratio of Lateral strain to its Linear (Longitudinal) Strain […]
