Since mechanical engineering is the broadest of all engineering fields, the job prospects on offer for skilled mechanical engineers are aplenty and unending. Mechanical engineers are required to design, test, manufacture, install, operate and maintain a wide array of machines and mechanical systems that are used in countless industries. These professionals can find employment both in the government and private sector undertakings.
Major industries that employ mechanical engineers include automobiles, space research, aeronautical, energy and utilities, air conditioning, bio-mechanical industry. Other major employers include giant manufacturing plants, air conditioning and refrigeration industry, turbine manufacturing plants, oil and gas exploration and refining industries and the agricultural sector.
In the government sector, mechanical engineers can provide their knowledge to various government run projects in the role of technical experts and consultants. They can also work in private engineering companies that provide technical consultancy to both government and corporate firms.
These engineers can also hold high managerial positions in government as well as private sector organisations according to their field of expertise and educational qualifications.
To make mechanical engineering your chosen career path, you must have affinity for the way different machines function. This trait can be observed from early childhood when children try to tinker around with different machinery in their immediate vicinity. Such kids often tend to take apart mechanical toys, clocks, bicycles and then they try to assemble them back again.
These children are so innovative that they may even try to make new things. Here, parents have a special role to play. They must understand that the child possesses an inquisitive mind that is interested in gaining knowledge about machinery and not in breaking or destroying things. Parents must encourage the child’s curiosity to know more about different gadgets and machines in and around the house.
During schooling, the quest to play around with machinery increases all the more. This curiosity often culminates with the child opting for science with the PCM subject combination.
Passing 10+2 with PCM (Physics, Chemistry and Mathematics) is the first step you take towards becoming a professional mechanical engineer. To be eligible for a graduate programme (BE/BTech) in a college, you should have scored at least 50% marks and 60% for being eligible for IITs (Indian Institute of Technology) in 10+2 with PCM as subjects. After this, you can sit for various entrance examinations such as:
• The Joint Entrance Examination for IITs (IITJEE) for admission to various IITs
• All-India Engineering Entrance Exam (AIEEE) for admission to various National Institutes of Technology or regional engineering colleges
Apart from these, there are hundreds of engineering colleges across the length and breadth of the country where you can get into a graduate programme in mechanical engineering. Some of these colleges conduct their own entrance exams whereas some accept AIEEE scores.
You can also opt for a diploma in engineering from a polytechnic. For obtaining a diploma, the basic eligibility is completion of Class 10 with 50% marks. The duration of these diploma courses is three-years for regular and four-years for part-time study.
You can also go for an associate membership qualification from the Institute of Mechanical Engineers, which is considered at par with the diploma earned from a state run polytechnic or a university degree. Another option is to earn a similar qualification offered by the Institution of Engineering (India). Diploma holders can also get direct entry into the second year of a graduate program (lateral entry).
After successful completion of the graduate program, you can go for the two-year masters program in mechanical engineering or ME/MTech. If you are interested in pursuing a post-graduate programme in mechanical engineering from any of the IITs, then you must appear for the Graduate Aptitude Test for Engineers (GATE).
These days many engineering colleges are offering a dual (BE/BTech and ME/MTech) programmes. Some other institutions are offering a combination of an engineering degree along with a management programme.
In case you are interested in further studies, you can go do a PhD or even opt for a management degree from a reputed business school.
Like other career paths, the entry into this particular branch of engineering also requires you to possess certain basic traits. First and foremost, you must have a penchant for mechanical components and machinery and how these machines work. Then you must be good at physics, chemistry and mathematics. You must also have skills such as an analytical bent of mind, logical reasoning and problem solving.
Further, you must have immense patience, physical strength, ability to work for long hours and an inventive spirit that are essential ingredients for becoming a successful mechanical engineer.
A graduate programme from a private engineering institution will cost you anywhere between Rs.50,000 to Rs.2,00,000 annually. However, in a reputed government run establishment such as the Indian institute of Technology (IIT) or any regional engineering college, you will have to pay an annual fees in the range of anywhere between Rs 30,000 to Rs 40,000.
Educational institutes offering programmes in mechanical engineering generally extend scholarships to students from socially and economically backward classes. For example, IITs waive off the complete tuition fees for students belonging to the socially backward communities. Scholarships, freeships, stipends and financial assistance are also provided to students on the basis of merit and other qualifying criteria.
Mechanical engineering offers a wide variety of career opportunities to job aspirants. The average monthly salary of mechanical engineers who are new to this profession is approximately in the range between Rs.10,000 and Rs.25,000. Good campus placements can fetch even better packages for deserving students. Mechanical engineers who hold a post-graduate degree from a reputed academic institute tend to get better offers than diploma and degree holders.
From here on the annual pay packet depends on a number of factors such as the skill set possessed, experience, expertise, the employer, nature of roles and responsibilities, etc. Highly skilled mechanical engineers can easily command pay packets as high as Rs 40-45 lacs per annum.
