Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. Mechanical engineering deals with anything that moves, including the human body. Mechanical engineers learn about materials, solid and fluid mechanics, thermodynamics, heat transfer, control, instrumentation, design, and manufacturing to understand mechanical systems. Specialized mechanical engineering subjects include biomechanics, cartilage-tissue engineering, energy conversion, laser-assisted materials processing, combustion, MEMS, microfluidic devices, fracture mechanics, Nanomechanics, mechanisms, micropower generation, tribology (friction and wear), and vibrations. Mechanical engineers design and assemble engines and power plants, structures and vehicles of all sizes. Mechanical engineers must have a solid understanding of base concepts such as mechanics, kinematics, fluid mechanics and energy.
Mechanical engineers play a central role in industries like automotive, aerospace, biotechnology, computers and electronics, micro-electromechanical systems, or MEMS, energy conversion like gas turbines, wind turbines, solar energy, fuel cells, environmental control, automation like robots, data and image acquisition, manufacturing.
AREAS OF SPECIALIZATION
Mechanical engineering is a broad field of technical education. Mechanical engineering is divided into various specializations are as follows-
UG (4 years)
To take admission into an undergraduate course in mechanical engineering, a candidate should have passed 10+2 in science stream form any recognised institution.
PG (2 Years)
To take admission into a postgraduate course, a candidate must have completed his/her Bachelor of Science/ B.Tech from any recognized university.
Diploma (3 Years)
Beside these, it is one of the broad research fields leading to the PhD (Doctor of Philosophy) degree.
Mechanical engineering is one of the top most career choices made by students in India. There are a lot of career opportunities in this field for young aspirants. Graduates from this field are mainly employed in manufacturing firms. Mechanical engineers can seek employment in private or public sector industries of various types. They can also find a job in government departments such as CPWD, defence, PWD. Other sectors such as electronics, chemical, power plants, steel plants, agricultural, space research institutes, automobile and aeronautical as well as the railways, need mechanical engineers to design and maintain their machinery. Candidates with a postgraduate degree or with additional management degree can find work in executive and managerial positions. In an agricultural division, mechanical engineers play a major role by establishing service centres for maintenance of pump sets, tractors, electric motors, oil engines and other agricultural equipment. Candidates who are interested in research activities can work with many public/private sectors research organizations. Professionals in this career can also opt for teaching jobs in universities and colleges. Postgraduate students with experience can also seek employment in abroad countries.
Major recruiters of India in this field are-
ISRO, DRDO, NTPC, COAL INDIA, ECIL, Tata Motors, Bajaj, Hero, Leyland, Ford, Honda, BARC, BHEL, ARMY, NAVY, HAL, SAIL.
