Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems.

A mechanical engineering course focuses on the design, development, analysis, and manufacturing of mechanical systems, encompassing topics like machine design, fluid mechanics, thermodynamics, solid mechanics, and manufacturing processes, essentially preparing students to work with machines, their components, and their operations across various industries like automotive, aerospace, energy, and manufacturing. It is considered one of the broadest engineering fields, often involving hands-on practical experience with CAD software and machine tools to design and build prototypes. 

mechanical engineering graduates can also work in automobile, aerospace, power generation, construction, and many more industries. Mechanical Engineers will also be recruited in government sectors like National Thermal Power Corporation (NTPC), Oil and Natural Gas Corporation (ONGC), Indian Railways, Regional Transport Officer (RTO), etc.
