Mechanical Engineering is a discipline within the engineering domain which deals with the application of the principles of science (especially Physics and Mathematics) and economics in the synthesis, analysis, design, manufacturing, installation, maintenance, and/or decommissioning of machines, tools, and systems, and materials in order to solve a problem or meet a need. This discipline serves to solve certain technical challenges facing society such as energy supply, provision of transport infrastructure like railways, and the manufacturing & the supply of needed materials such as steels and other alloys.

Mechanical Engineering is a very broad discipline which includes the following subdisciplines: Metallurgy, Thermal Engineering, Automotive Engineering, Production Engineering, Manufacturing Engineering, and Mechatronics.
Mechanical Engineering is integral to other disciplines like Aerospace & Aeronautical Engineering, Electrical Engineering, and Civil Engineering.

People who practice or study Mechanical Engineering are called mechanical engineers. An undergraduate programme usually involves the study of such courses and subjects like solid mechanics, thermodynamics, fluid mechanics, mathematics, basic electrical/electronic principles, and control theory.

Badass Mother Fuckers that are way under paid unless they move to a big city.
Scott (new hire): Is that a bum over there?
Andy (plant manager): No!, lol, That is our Mechanical Engineer, I barely pay him to design all of our badass equipment. He looks like a bum because he is still paying for his $50K education and can barely afford to make his house payment. Not to mention that President NoBama has his head shoved up his own ass!

I heard you study mechanical engineering.

Actually Anjali, it’s pronounced “best college major.” I can understand your confusion tho, you’re not the brightest bulb on the tree.

One so prone to metacognition as to overlook the obvious.
A Mechanical Engineer may design an escape from a labyrinth only to crash to the sea.
