Mechanical uses in future

Design of machine
Thermodynamics analysis
Fluid analysis
Finite element Analysis
Strength of materials
Computer aided design And manufacturing
Power plant engineering

All these requires a good mechanical engineer

Mechanical engineering is known as the evergreen branch among all the other branches of engineering. Traditionally, mechanical engineers have to deal with concepts such as mechanics, thermodynamics, robotics, kinematics, structural analysis, fluid mechanics with their applications in Automotive Sector, Power Sector, Refrigeration and Air Conditioning Sector, Aerospace.

Assuming you are asking for scope of Mechanical Engineering so you can consider below details -

Mechanical Engineering is one of the oldest branch in engineering,Another remarkable advantage of Mechanical Engineering is that its scope is everlasting. And masters in mechanical engineering can get career placements in almost every sector, from steel industry to automobile and from construction to software. Also, it has a wise scope of jobs in public, private and abroad as well like -

Private Sector -
You can job in major mechanical companies in India such as: Siemens, Indian Oil, Tata Motors, Larsen and Toubro, Mahindra & Mahindra, Toshiba and Reliance Industries etc, Major industries in private sector suitable for M. Tech. degree holder in mechanical engineering are: Automobile, Power & Energy, Oil & Gas, Chemical and Construction etc, you can also work in logistics & auto engineering firms as consultant.

Government Sector -
A Government sector job is considered more safe & secure in comparison to private sector jobs, but you have to keep in mind that salaries in Government sector are not as high as in private sector. Some of the popular industries in the govt. sector are:
Public Sector Undertaking (PSU)
India Defense Services
India Railways/Metro Rail
Government Power & Energy Organizations
State Government  engineering division

Job Overseas -
There are a number of excellent quality mechanical research centers in abroad. One of the top notch firms that hire masters in mechanical engineers is Ford. United States, Japan & Korea are some of the countries where post graduate in mechanical engineering, distinctively specialized in automobile engineering, can find good jobs.

Hope this helps!!!
