Mechanical Engineering has application in every field of Technology. It is considered to be the evergreen trade. The working style of Mechanical Engineers changes depending on the type and domain of the company they are working with. The need of Mechanical Engineers has raised exponentially over time with the drastic increase in the Industrial Sector. They have tremendous scope in automobile engineering, steel, power sector, Petroleum, Aeronautical and many more. They can also find job very easily in public sector industries such as Indian Railways,Indian Army etc. In modern life virtually every product or services has probably been touched in some way by a mechanical engineer.
