Mechanical Engineering

 Introduction to Mechanical Engineering:

Mechanical engineering is the application of physical principles to the creation of useful devices, objects and machines. Mechanical engineering is deals with the applied mechanics, dynamics, thermodynamics, fluid mechanics, electricity, production technology.

The branch mechanical engineering applies principles of engineering, physics and material science for the design, analysis, production, and operation of machinery, manufacturing and maintenance of mechanical systems.

In addition to these core principles, mechanical engineers use tools such as computer aided design (CAD), and product life cycle 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.

Mechanical engineering is a professional programmer which helps students to understand the working mechanisms of heavy tools and machineries.
