Mechanical engineering is a branch of engineering that applies the principles of engineering, physics and material design for the design, production and operation of machinery.
Mechanical engineers use principles of mechanics, thermodymanics, electricity, materials Science and others to design and analyze manufacturing plants, industrial equipment, machinery, aircraft, robots, weapons and others.
Mechanical engineers create and build mechanical devices. They apply the fundamentals of Science and math to create practical, useful solutions that the rest of us can use.
There is a huge demand for skilled mechanical engineers in India and abroad. The expertise of a mechanical engineer is required in manufacturing industries like automobiles, aviation, etc. In the recent times and due to the advent in technology, the skills of a mechanical engineer is sought in fields such as nano-technology, biomedical engineering, energy conservation and more. According reports, the growth in this industry it is said within the next few years, mechanical engineering will be the highest paid career option.
All the best.

You can get good private college, but now a days getting into a college is not important. The thing that is important, is which branch you choose.
Computer science and Automation and Robotics are two branches having great scope in future.
I would suggest Gulzar Group of Institution for these two branches, as Gulzar Group of Institution is 3rd college in India to have KUKA certified training in automation and robotics. For CSE, it has signed MoU with L-Kshay Pvt. Ltd. company that has established a CODERS Club in which students are made to learn working on live projects to enhance their practical and theoretical knowledge, and have an exposure and certification of working with MNC being in college and have a knowledge of cooperate world.
