About the Department
Dr. Tom, what is mechanical engineering?
Engineering in general has been defined as "applying
creativity, mathematics and science to solve
problems within economic constraints". Mechanical
Engineering is the broadest of all the engineering
disciplines in terms of scope, and thus this
definition could well apply to mechanical engineering
too. Engineering was once largely a trial and
error endeavor. (That looks strong enough - D'oh!)
Now it relies heavily on the scientific method
in the research, design, and production of products
and processes. Specifically, the "science" in
mechanical engineering refers to the mechanical
sciences, a term which loosely describes those
aspects of physics which are mechanical in nature.
But we'll see that even this may be a bit too
restrictive. For example, Heat Transfer is not
particularly mechanical, but it is a major focus
of mechanical engineering.
That
seems pretty broad, so let me ask this. What
does a Mechanical Engineer do?
The short answer is everything! A little more
specifically, one could break the functions
of a mechanical engineer (ME) into four categories:
Analysis and modeling of systems: The
ME must understand the basics of mechanical
science, which include, but are not limited
to:
- Dynamics
- the relation between forces and motion,
such as in vibration
- Machines
- the analytic study of planar linkages, gear
trains, cams, governors, flywheels and gyroscopes
- Automatic
Control - controlling machines and systems
based on feedback from the systems themselves
- Thermodynamics
- the relations among the various forms of
heat, energy, and power Fluid Flow - the relation
between forces and motion in fluids
- Heat
Transfer - the transport of thermal energy
due to temperature differences, including
conduction, convection and radiation
- Materials
- properties of metals, ceramics, polymers,
and composites including strength, stress
and strain An ME uses her/his knowledge of
these sciences to analyze and predict the
behavior of systems. These systems may be
real, existing systems, or they may be imaginary
systems that someone is thinking about building.
Design, research and development : The
mechanical engineer doesn't just perform calculations
all day. She uses her knowledge and ability
to solve real world problems by creating new
products and processes, as well as improving
existing ones. When engaged in design, the mechanical
engineer creates something that has never existed
before, whether that is a product or a process.
In addition to being a highly creative endeavor,
the design process involves careful planning,
evaluation of alternatives, and the production
and testing of prototypes.
There
are a lot of things we still don't know about
the mechanical sciences, and sometimes the solution
to a problem involves a process or technique
unlike anything anyone has ever seen. The mechanical
engineer who devotes herself to these areas
is engaged in research and development. The
research and development specialist is often
at the cutting edge of new technology.
Production of products and processes
: It's not enough simply to analyze and develop
stuff. If a real life problem is going to be
solved, eventually something has to be built.
But sometimes the problems involved with building
a device are tougher to solve than the problem
the device is supposed to solve! The operation
and maintenance of the resulting equipment is
no picnic either.
MEs
are involved in all of these processes, and
aim to maximize the value of products and processes
while at the same time minimizing cost. Manufacturing
engineers are often specialists in this area.
The ME as coordinator : Engineering doesn't
exist in a vacuum. MEs must interact with many
people from other fields, and are often called
upon to take on some of those roles. These include
management, consulting and, in some cases, marketing
and technical sales. Many MEs perform a great
number of these other functions, and might call
their profession engineering management something
of a hybrid between business and engineering.
A
mechanical engineer most likely performs some
of all these functions at one point or another.
Most mechanical engineering jobs, however, emphasize
one of these functions over the others.
Can
you give me some typical employers of MEs?
The list is almost as big as industry itself.
ALLTELL Corporation, Andersen Consulting, Caterpillar,
Cummins, Cybo Robots, Dow Chemical, Ford Motor
Company, GE Corporation, Ingersoll-Rand, Johnson
Controls, Lockhead-Martin, Milliken, NASA, Otis
Elevator, PSI Electric Company, Raytheon, Rocketdyne,
Schlumberger, Trane and Wavetek all employ lots
of MEs. There are countless others.
MEs needn't work just in industry, however.
The well-roundedness of an undergraduate degree
in mechanical engineering gives you an excellent
background to go to law school, medical school
or business school. You can even combine the
areas of expertise to become a sought-after
specialist. (Patent lawyers are a good example.)
Why, you might even end up as an educator like
me!

You should also talk to a mechanical engineer.
Chances are that you know one, or at least someone
you know knows one.
To provide the curriculum, the educational environment, and
the individual support necessary to graduate mechanical engineers
who are technically competent, effective in practice, creative, ethical
and mindful of their responsibility to society.
To graduate the best baccalaureate mechanical engineers.
The mechanical engineering curriculum is designed to prepare students for productive careers
in industry, government, education, and private consulting as well as for graduate study.
In the early phase of their careers, we expect our students to:
- Apply engineering fundamentals to problem solving processes in an iterative manner.
- Design effectively.
- Continue to learn and educate themselves.
- Communicate effectively.
- Work responsibly.
- Work effectively.
Learning outcomes are the abilities that we expect mechanical graduates to possess. They are as follows:
Ethics - A recognition of ethical and professional responsibilities
When given the opportunity, students will:
- Demonstrate knowledge of professional codes of ethics.
- Evaluate the ethical dimensions of professional engineering, mathematical, and scientific practices.
