We know what is a mass moment of inertia, it is a resistance force of a physical object to any change in its state of motion, But what is a polar moment of inertia? By definition Polar Moment of Inertia is a measure of resistibility of a shaft against the twisting. Polar moment of inertia […]

# 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.

## 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 […]

## 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 […]

## What is Least Material Condition (LMC) in GD&T?

In the Design of any machine elements, it is necessary to follow the Geometric dimensioning and tolerancing for the Holes or shafts. The Least Material Condition(LMC) is the feature of the size where it can be called out for a hole or a shaft feature on the drawing. Least Material Condition (LMC) It refers to a feature […]

## What is Maximum material condition (MMC) in GD&T?

In the Design of any machine elements, it is necessary to follow the Geometric dimensioning and tolerancing for the Holes or shafts. The maximum material condition is the feature of the size where it can be called out for a hole or a shaft feature on the drawing. Maximum Material Condition (MMC) It refers to a feature […]

## What are the Mechanical properties of materials in Engineering?

The Design of any Machine elements will be started at the Material selection and the study of the Mechanical Properties of Materials. Following are the different mechanical properties of materials. Let’s see each of them. Mechanical Properties of Materials 1. Elasticity The ability to deform with respect to the applied load and regain its original […]

## Fuel Tank Calibration in Automobiles

Automobiles in the present day are highly advanced. No need to introduce it. The developments are very high in terms of engine capacity, efficiency, BHP, lighting, braking and much more. The area of the automobile where there is a higher scope of development is “FUEL TANK AND ITS CALIBRATION”. Till date, there are only very few technologies […]
