What is Mechanical Engineering?
• 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.
• It is one of the oldest and broadest engineering
disciplines.
Mechanical Engineering-2013
7
What is Mechanical Engineering?
• The engineering field requires an understanding of core
concepts
including mechanics, kinematics,thermodynamics, materi
als science, structural analysis, and electricity.
• 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, transport
systems, aircraft, watercraft, robotics, medical devices,
and others.

What is Mechanical Engineering?
• 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.
Mechanical engineering science emerged
in the 19th century as a result of
developments in the field of physics.
Mechanical Engineering-2013
9
What is Mechanical Engineering?
• The field has continually evolved to incorporate
advancements in technology, and mechanical
engineers today are pursuing developments in
such fields as composites, mechatronics,
andnanotechnology. Mechanical engineering
overlaps with aerospace engineering, building
services engineering, metallurgical
engineering, marine engineering, civil
engineering, electrical engineering, petroleum
engineering, manufacturing engineering,
and chemical engineering to varying amounts.

The Eiffel Tower (completed 1889) is
an iron lattice tower located on the Champ de
Mars in Paris, named after the
engineer Gustave Eiffel, whose company
designed and built the tower. The tower stands
320 metres (1,050 ft) tall, about the same height
as an 81-storey building.

Professional Registration - USA
• In the U.S., to become a licensed Professional Engineer,
an engineer must pass the comprehensive FE
(Fundamentals of Engineering) exam, work a given
number of years as an Engineering Intern
(EI) or Engineer-in-Training (EIT), and finally pass the
"Principles and Practice" or PE (Practicing Engineer or
Professional Engineer) exams.
• In the United States, the requirements and steps of this
process are set forth by the National Council of
Examiners for Engineering and Surveying (NCEES), a
composed of engineering and land surveying licensing
boards representing all U.S. states and territories.

Outlook for the Future
• The demand for improved machinery, machine
tools, and complex manufacturing processes is
creating a growing demand for mechanical
engineers.
• In addition, new areas such as
nanotechnology, microelectromechanical
systems, and bioengineering are creating
opportunities for mechanical engineers.
Mechanical Engineering-2013
38
Outlook for the Future
• Other opportunities are expected to be in
the engineering services area
(engineering consulting firms) as
manufacturing companies contract out
design, development, and testing work to
solve engineering problems.
