Mechanical engineering is one of the oldest and broadest engineering disciplines. Mechanical Engineering is a discipline that tends to focus on analysis, design, manufacturing, and maintenance of mechanical systems. Mechanical engineering apply the core principles of mechanics, kinematics, thermodynamics, fluid mechanics, and energy as well as other knowledge in the field to design and analyze motor vehicles, aircraft, heating and cooling systems, watercraft, manufacturing plants, industrial equipment and machinery, robotics, medical devices etc. Specializations area in mechanical engineering include subjects like: Robotics, Computer aided designs, Biomechanics, Automation, Thermal/Fluids, Engineering Systems and Design Engineering. Materials Science Engineering Mechanical engineers research, design, develop, manufacture, and test tools, engines, machines, and other mechanical devices. They work on power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines. They also work on power-using machines such as refrigeration and air-conditioning equipment, machine tools, material handling systems, elevators and escalators, industrial production equipment, and robots used in manufacturing. Mechanical engineers also design tools that other engineers need for their work. In addition, mechanical engineers work in manufacturing or agriculture production, maintenance, or technical sales; many become administrators or managers.

For a diploma in Mechanical engineering, one must clear the 10th Std. board exam successfully with at least 50% marks. To be eligible for bachelor's degree course i.e. B.E or B.BTech, one must clear the 12th std. board exam with at least 50% marks(60% for IITs) in the science stream with Physics, Chemistry and Maths as compulsory subjects.Selection to the graduate courses ( BE / B.Tech ) is based on merit i.e the marks secured in the final exams of 10+2 and through entrance exams. Entrance to the IIT's is through JEE' (Joint Entrance Exam) and for other major institutions through AIEEE (All India Engineering/Pharmacy/Architecture Entrance Examination) or their own separate entrance exams and other state level and national level exams.

 With the rapid rate of expansion in the industrial sector, the employment potential for mechanical engineers is very high. Mechanical engineer can explore employment opportunities with many industries including private or public sector industries of various types, and their work varies by industry and function. These engineers are required in automobile, chemical, electronics, steel plants, oil exploration and refining, technical wings of armed forces, space research organisation, etc. for maintenance of tractors, oil engines, pump sets, electric motors and other agricultural equipments. Some of them most important positions and their nature of work are:

There are 36 universities and 1195 colleges offering undergraduate and postgraduate engineering courses in various branches in India. All the engineering colleges / institutions in India are recognized and regulated by All India Council of Technical Education (AICTE).
