Mechanical Engineering

Mechanical engineering deals with the design, manufacture and operation of mechanical systems, and is one of the oldest branches of engineering. Technically, mechanical engineering is the application of the principles and problem-solving techniques of engineering from design to manufacturing to the marketplace for any object. Mechanical engineers analyze their work using the principles of motion, energy, and force, ensuring that designs function safely, efficiently, and reliably, all at a competitive cost.
The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, and electricity. Mechanical engineers may use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, robotics, medical devices, weapons, and others.
Mechanical Engineering covers aspects like design and testing among others. The job demands supervision and planning of live projects related to thermal power plants, nuclear stations, generation of electricity, etc.
The emerging fields in this area include renewable energy, automobiles, quality control, Industrial Automation, Mechanobiology. These are going to increase manpower in the work profile of mechanical engineering and would offer employment opportunities.


Engineering Courses are available in different levels:

Diploma in Engineering is 3-year job-oriented courses offered by Government as well as Private institutes across India. There several Polytechnics and Technical Institutes offer Diploma courses. Usually the basic qualification required is 10th grade.

B.E (Bachelor of Engineering) / B.Tech (Bachelor of Technology) is the professional undergraduate engineering degree programme, which is of 4 years (8 semesters) duration. BE/BTech is your gateway to a career in engineering. Some colleges offer BE, while other colleges offer BTech. Conceptually BE is more theoretical and knowledge oriented, whereas BTech is skill oriented and has more focus on application of engineering.

Usually BTech is 4 years after +2. For those who have completed Diploma in Engineering, there is an option to complete BTech in 3 years.

M.E (Master of Engineering) / M.Tech (Master of Technology) is a two year (4 semesters) professional postgraduate program, after successful completion of BE/BTech. ME/MTech degree is offered across various specializations. The entry for ME/MTech is via GATE (Graduate Aptitude Test in Engineering).

Required Skills

Each branch of engineering requires a specific skillset. However, in general the skills required for engineering include:

  • Logical Thinking, Critical Thinking & Problem Solving
  • Analytical & Creative thinking
  • Communication Skill – Verbal and written
  • Application of the knowledge in Mathematics and Science
  • Motion Concepts
  • Familiarity with Industry Standards
  • Ability to work as team
  • Leadership Skills

Eligibility Criteria

The basic eligibility requirement for admissions to any BTech programme is:

  • Candidates must have passed Class 10+2 exam from a recognised board with Physics, Chemistry and Mathematics as core subjects.
  • They must also have secured a minimum aggregate mark of 60% in the above subjects combined.

The eligibility criteria may vary from institute to institute.

The basic eligibility for Diploma courses is 10th grade pass.

Entrance Examination

JEE Main is the main entrance examination for BE/BTech admission in important institutes including National Institute of Technology (NIT), Indian Institute of Information Technology (IIIT), Government Funded Technical Institutes (GFTI), etc.

JEE Advanced is the entrance for BE/BTech admission in Indian Institute of Technology (IIT).

State Level Engineering College admission is based on state level entrance exams, for example:

  • Kerala Engineering Agriculture and Medicine (KEAM)
  • Tamil Nadu Professional Courses Entrance Examination (TNPCEE)
  • Karnataka Common Entrance Test (KCET)
  • Andhra Pradesh APEAMCET

For most state level entrance examinations, 50% weightage is for Board Exams.  

GATE (Graduate Aptitude Test inEngineering) is the entrance for ME/MTech postgraduate programs.

IITs also offer postgraduate program (MTech) and Bachelor-Master dual degree (BTech + MTech in 5 years) and Doctoral degree (PhD).

National Institutes of Technology (NITs) is there one in most states. There are 31 NITs with a total intake of over 10,000 for BTech undergraduate programs. Most NITs offer MTech as well as Bachelor-Master dual degrees.

Government Funded Technical Institutes (GFTI). There are 23 GFTIs with a total intake of over 9,000 seats for BTech. 

In every state in India, there are Government Engineering Colleges, Aided Engineering Colleges and Self-Financing Engineering Colleges. State Level Engineering Colleges are available in this link.

Before joining a course, please ensure that the course in the given institution is approved by AICTE (All India Council for Technical Education). 

Polytechnics offers three years Technical Diploma Courses in various branches of Engineering. Admission to Polytechnics in some states is based on 10th grade marks and others are based on entrance exams. 

Questions & Answers​

[Q]: What is the suitability test at IIT Madras for MTech admission in the Mechanical Engineering Department?

[A]: Suitability test is in IIT Madras campus is a screening test where the respective faculty of the concerned discipline will give a presentation on  the particular engineering domain in MTech course. After the presentation, there will be an interview session, in which you will be asked questions to check your passion in that particular discipline, your goal for MTech course etc.

[Q]: What are my options as a Mechanical Engineering student, if the on campus placements in my college are not good?

[A]: You do have a few options as follows:

  • Strengthen your Profile – Take up some other courses like CAD softwares, Review some Papers.
  • Join LinkedIn,, or other online job portals
  • Search for Jobs in your City/ State.
  • List a few companies you would like to work for and send them your Resume and cover letter

[Q]: What is the difference between Masters of engineering: mechanical engineering or Masters of science: mechanical engineering?

[A]: Different Universities have their degrees offered as either Masters of Technology (M.Tech), Masters of Science (M.S or M.Sc) while some offer Masters of Engineering (M.E). The course content and credits offered are relatively the same at all universities for their relevant academic schedule. It is safe to talk to the departments of relevant Universities while comparing the degree offered and their duration.

[Q]: Can Mechanical Engineering Freshers Work In IT Companies?

[A]: Yes, a mechanical engineering fresher has opportunities in IT companies considering your knowledge of science and mathematics to carry out the work in hand after a little training. Please keep in mind before taking up a job in an IT company that you are most probably leaving your domain behind and taking up a job that will require you to work hard in order to push themselves up. In order to get the job, it will be good to brush up your knowledge in C/C++/Java and some software development tools.
