Mechanical Engineering is the discipline that applies the principles of engineering, physics and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. Anything that can move, become the subject of mechanical engineering right from electric fans to most complex our own human body.
Mechanical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices to large systems like heavy cranes.
