Mechanical engineering is one of the oldest and broadest branches of engineering. Mechanical engineering applies the principles of engineering, physics and material design for the design, production and operation of machinery. Mechanical engineers have to deal with concepts such as mechanics, thermodynamics, robotics, kinematics, structural analysis, fluid mechanics and many others. These concepts are applied in designing state of the art manufacturing units, automobiles, aircraft, aerospace parts and industrial machinery.
Mechanical engineers also help develop various engines, power plant equipment, heating and cooling systems, in short from simple to complex machinery. They are also involved in the testing, maintaining and manufacture of mechanical systems. The current scope of Mechanical engineering is expanding beyond its traditional boundaries to areas like nanotechnology and biomedical applications.
Mechanical engineering field has a healthy growth rate every year with plenty of job opportunities. Another advantage of mechanical engineering is that once you have done a B.Tech in Mechanical you can opt to specialize in other areas like aerospace, automotive and many such fields. It you are interested in R&D you can get employed in many public/private research organizations. With the rapid expansion in the industrial sector, the demand for mechanical engineers is ever increasing.
Industries/Companies who hire mechanical engineers:
- Automobile and auto part manufacturers
- Aerospace industry
- Aviation companies
- Steel plants
- Thermal plants
- Air conditioning and refrigeration industry
- Shipping industry
Mechanical engineers have employment opportunities in both private and public sectors. Government sectors like Defence, PWD, Railways etc hire mechanical engineers. There are umpteen private companies that hire mechanical engineers, SIEMENS, L&T, Tata Motors etc are some of the big private firms to name a few. There are also equal opportunities outside India.
