MECHANICAL ENGINEERING



MECHANICAL ENGINEERING is the one of the oldest departments .
A mechanical engineer had ,has and will have a good demand.
Each and every industry begin put up needs a mechanical engineer and its a VAST subject.
This particular branch has many sub divisions ,which may be broadly divided into
1)Heat& thermodynamics.
2)Manufacturing.
3)Machine design.
4)Machines.

HEAT & THERMODYNAMICS

This can be defined as the heart of the mechanical engineering.
This mainly deals with the heat which may be further divided into
a)Refrigeration and Air conditioning, which may be further divided into crogenics (dealing with temperatures below 120k)
b)Combustion :This deals all the combustion processes taking place in engines.
c) Heat transfer:This deals with processes like convection,conduction,radiation which are being used in the development of solar energy concepts,thermal power plant engineering etc.
d)GAS dynamics : This particular area is developing htese days and lot of reasearch is going on these days in computational fluid dynamics.

Manufacturing:

This is another important part of the mechanical engineering mainly dealing with the various conventional and modern methods of producing machine parts and processing techniques.
This you can say is a kind of dry subject where u come across various machines used for producing parts.
In this area the importance is given for developing methods to get parts machined parts with greater surface finish and quality,reducing wastes during producing parts,developing new modern methods for solving the problem of huge waste.
The modern methods include processes of converting one form of energy to another in order ot get parts machined .ex:using water jets,lasers,electron beams etc to remove material.
A lot of research is going on these modern methods which is quite interesting..

Machine design:

In the current world a lot of credit is begin given to manufacture things with grater compactness.This is what is begin dealt in this part.
this has huge huge demand ,like designing of cars of very small size.
This mainly deals with the designing of parts to work under particular constraints, taking decisions like which material can be used to replace a particular material for many reasons like weight constraint,thermal behavior etc.

To conclude this is a very interesting area with a lot of thing to be explored

Machines:

This part may be said to contain many things which we can see in daily life having greater usage and importance like automobiles,fans,turbines etc.
This part will provide you with the basic concepts and working principles of the machines.This one too is an interesting area with a lot to be explored.

Nice article sir. I am an engineering aspirant and want to get into IIT or NIT and want to work in designing of cars. Can you write an article on the field of designing in mechanical engineering?
waiting for your article
