Mechanical engineering is the study
of physical machines that may involve force and movement. It is an
engineering branch that combines engineering physics and mathematics
principles with materials science, to design, analyze, manufacture, and
maintain mechanical systems.It is one of the oldest and broadest of the
engineering branches.
Mechanical engineering requires an
understanding of core areas including mechanics, dynamics, thermodynamics,
materials science, structural analysis, and electricity. In addition to these
core principles, mechanical engineers use tools such as computer-aided design
(CAD), computer-aided manufacturing (CAM), 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 emerged as a
field during the Industrial Revolution in Europe in the 18th century; however,
its development can be traced back several thousand years around the world. In
the 19th century, developments in physics led to the development of mechanical
engineering science. The field has continually evolved to incorporate
advancements; today mechanical engineers are pursuing developments in such
areas as composites, mechanics, and nanotechnology. It also overlaps with
aerospace engineering, metallurgical engineering, civil engineering,
structural engineering, electrical engineering, manufacturing engineering,
chemical engineering, industrial engineering, and other engineering
disciplines to varying amounts. Mechanical engineers may also work in the
field of biomedical engineering, specifically with bio mechanics, transport
phenomena, microelectronics, bio nanotechnology, and modelling of biological
systems.
