Hello everyone

This is the mechbloggiees team wholeheartedly welcoming you to our first blog !!!

In this blog and even many more to come, we are going to take you to a remarkable journey which paves the way to mechanical engineering discipline. So let’s embark upon this journey and begin the trip !!!

So, Firstly not to bore you much with a long gggg facts about mechies, we have a short definition to throw some light on what actually being a mechanical engineer means from its root.

Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyse, manufacture, and maintain mechanical systems.

Basically the mechanical is the combination of many branches such as the civil, electronics in many aspects you will slowly understand the application of other branches in the mechanical field even you will understand why the people say the mechanical as the mother of all branches…

Done with the definition??

S, Let’s jump right into its core divisions which are as :

Design
Analysis
Testing
Manufacture

I. DESIGN

Introduction

Engineering design is basically the process of devising a system, components, or process to meet the desired needs.

It is a decision making process (often iterative), in which the engineering sciences and mathematics are applied to convert resources optimally to meeta stated objective.

2. Mechanical Design

Mechanical design means the design of components and systems of a mechanical nature — machines, products, structures, devices and instruments. It uses mathematics, materials, and the engineering mechanics sciences and various engineering graphics techniques.

Mechanical engineering design includes all mechanical design, but it is a broader study because it includes various disciplines of mechanical engineering such as thermal, fluid, heat transfer, structural aspects etc.

II. ANALYSIS

Introduction

Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it.

The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.

Analysts in the field of engineering look at requirements, structures, mechanisms, systems and dimensions. Electrical engineers analyse systems in electronics. Life cycles and system failures are broken down and studied by engineers. It is also looking at different factors incorporated within the design.

2. Engineering Analysis

Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of a system, device or mechanism under study.

Engineering analysis is decompositional: it proceeds by separating the engineering design into the mechanisms of operation or failure, analyzing or estimating each component of the operation or failure mechanism in isolation, and re-combining the components according to basic physical principles and natural laws.

The most common design analysis application in the field of mechanical engineering is stress analysis. Engineers study the stresses (both structural and thermal) on a part to determine whether it will fail or not and whether design modifications are necessary to overcome potential problems.

III. TESTING

Introduction

Testing of the designed part is the same as the impact on the part in the real world such as accidents in the real life and impact of force on the part in the machinery.

Materials testing breaks down into five major categories: mechanical testing; testing for thermal properties; testing for electrical properties; testing for resistance to corrosion, radiation, and biological deterioration; and non-destructive testing.

These are simulated on the designed part by using some of the experimental techniques and the output is taken into consideration for confirmation of the design and also the materials to produce the design.

2. Mechanical Testing

Mechanical testing reveals the properties of a material under dynamic or static force. Designed to ensure that materials are suitable for their intended applications, mechanical testing includes methods such as tensile strength, compression strength, impact resistance, fracture toughness and fatigue.

Mechanical testing covers a wide range of tests, which can be divided broadly into two types:

those that aim to determine a material’s mechanical properties, independent of geometry.
those that determine the response of a structure to a given action, e.g. testing of composite beams, aircraft structures to destruction, etc.

IV. MANUFACTURING

Introduction

It’s the one of the major division of the mechanical engineering. It’s basically the production of products for use at a higher rate using the machines and work force.

We can order it as the third process in the whole manufacturing process. The design aspect of the part comes first and the testing aspect of the designed part comes second followed by the production process.

2. Mechanical Manufacturing

In terms of mechanical engineering the production is the process of making the final required products of the raw materials this entire process is termed as the manufacturing.

The major jobs in the field of mechanical engineering is the manufacturing industries as per the stats of India we can infer that the production recruitment was higher in the year 2014 and lower in 2019.
