which is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems.
The engineering requires all concepts of engineering field including mechanics, kinematics, thermodynamics, structural analysis, and electricity. It is the branch of engineering that involves the design, production, and operation of machinery. Thus, mechanical engineers people who response in the design, development, production of equipment and systems controlling for safety, quality and efficiency.
