Mechanical engineering is a discipline of
engineering that applies the principles of
physics and
materials science for analysis, design,
manufacturing, and maintenance of
mechanical systems. It is the branch of engineering that involves the production and usage of
heat and mechanical power for the design, production, and operation of machines and
tools.
[1] It is one of the oldest and broadest
engineering disciplines.
The engineering field requires a solid understanding of core concepts including
mechanics,
kinematics,
thermodynamics,
materials science, and
structural analysis. Mechanical engineers use these core principles along with tools like
computer-aided engineering and
product lifecycle management to design and analyze
manufacturing plants, industrial equipment and machinery,
heating and cooling systems, motorized vehicles,
aircraft,
watercraft,
robotics,
medical devices and more.
Mechanical engineering emerged as a field during the
industrial revolution in Europe in the 19th century; however, its development can be traced back several thousand years around the world. The field has continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as
composites,
mechatronics, and
nanotechnology. Mechanical engineering overlaps with
aerospace engineering,
civil engineering,
electrical engineering, and
petroleum engineering to varying amount
