Mechanical Engineering is an Engineering discipline that involves the application of principles of physics for analysis, desing, manufacturing, and maintanance of mechanical systems. Mechanical Engineering is one of the oldest and broadest engineering disciplines. It requires a solid understanding of core concepts including mechanics, kinematics, thermodynamics, fluid mechanics and energy. Mechanical engineers uses the core principles as well as other knowledge in the field to design and analyze motor vehicles, aircraft, heating and cooling systems, watercrafts, manufacturing plants, industrial equipments and machinery, robotics, medical devices and more.
