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 […]

# MECHANICAL ENGIEERING

Mechanical Engineering is the discipline that applies engineering, physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

Understanding of Mechanical engineering involves core areas including the Mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity.

In this Edublog, we help you understand the Basic engineering concepts, the engineering principles, definitions, laws, derivations and functionalities of machines in the following subjects with the help of concise articles, tutorials and step by step guides prepared by the Senior engineering Experts for free.

- Metrology
- Machine Design
- Production Technology
- Material science
- Strength of Materials
- Dynamics of Machinery
- Engineering Mechanics
- Mathematics
- Hydraulics and Pneumatics
- Automobile Engineering

We also feature on youtube to help you with the engineering concepts, the engineering principles, definitions, laws and functionalities of machines, using CAD programs in machine design(CAD), engineering(CAE), manufacturing(CAM) and advanced Excel tools to automate the methods into Tools.

## 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 what is inertia. Let’s have a deep look into it. What is Inertia? By definition Inertia is a […]

## 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 […]

## What is Regardless of feature size (RFS) in GD&T?

In Design of any machine elements, it is necessary to follow the Geometric dimensioning and tolerancing for the Holes or shafts. The Regardless of feature size(RFS) is the feature of the size where it can be called out for a hole or a shaft when there is no need of MMC or LMC. Regardless of feature […]
