MMechanical engineering is the discipline that applies the principles of Engineering, Physics and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems.
It is the branch of engineering that involves the design, production, and operation of machinery. It is one of the oldest and broadest of the engineering disciplines.This branch is spread not only to automobiles but also to machinery works as well as automation machines.
The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided design, and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems,aircraft,watercraft, robotics, medical devices, weapons, and others.
