Mechanical Engineering

DEPARTMENT OF MECHANICAL ENGINEERING
Mechanical Engineering is an engineering discipline that was developed from the application of principles from physics and materials science. According to the American Heritage Dictionary, it is the branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. It is one of the oldest and broadest engineering disciplines.
The field requires a solid understanding of core concepts including mechanics, kinematics, thermodynamics, fluid mechanics, heat transfer, materials science, and energy. Mechanical engineers use the core principles as well as other knowledge in the field to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, motor vehicles, aircraft, watercraft, robotics, medical devices and more.
The department is well equipped with a gamut of specialized equipments in the laboratories to provide sound knowledge of the subjects by performing experiments. Rigorous workshop training in the areas of machine shop, carpentry, welding, sheet metal and foundry etc. form an inextricable part of the curriculum.
The department is has state of art facilities to impart quality education to the students. The department also boost of having distinguished, dedicated and competent faculty members to impart quality education, project guidance, personality development, group discussion and self esteem enhancement of the students to enable them to pursue a successful career ahead.
