5Mechanical Engineering Is
Much more than working with cars!!!
Even the best cars!
6Mechanical Engineering Is
- Finding creative solutions to problems!
- Perhaps the broadest of all the engineering
disciplines. - Working with motion, energy, forces, and
materials. - Concerned with analysis, design, manufacture and
operation of areas such as - Energy
- Defense
- Environment
- Health Bio
- Manufacturing
- Transportation
Scientists discover the world that exists
engineers create the world that never was.

15Mechanical Engineering Research
- ENEMY DETECTION
- A new sensor that measures the motion created by
sound waves under water could allow the U.S. Navy
to develop compact arrays to detect the presence
of enemy submarines. - These compact arrays would detect quiet
underwater targets, while providing very clear
directional information.
- The novel underwater sensor uses optical fibers
to detect the direction from which a sound is
coming under water. - This directional component is an important
improvement over the current technology.
16Mechanical Engineering Research
- MATERIALS MAY SOON AID ORTHOPEDIC SURGERY
- Motivation To develop devices that may soon
improve the treatment of human orthopedic
conditions. - Details
- The research focuses on shape-memory polymers
and alloys solid materials that can change shape
on demand. - The ability of these materials to mold actively
to human bone and tissue will make them useful in
reconstructive surgery. - Examples of the product applications are for use
in knee surgery and those with diabetes who
develop ankle pain.
17Mechanical Engineering Research
- ACTIVE CONTROL OF AUTOMOTIVE DISC BRAKE SQUEAL
- Objective To investigate the use of dither
control (intentionally applied noise) for the
suppression of automotive disk brake squeal for
GM. - Overview Theoretical and experimental models
are being used to develop an improved
comprehension of the dynamics involved.
- Experimental Setup The experimental set-up
(using a brake dynamometer) measures braking
pressure, brake pad temperature, the normal force
on the brake pads, braking torque, in-plane
velocity of brake pads and rotor and acoustic
measures with a microphone.
18Mechanical Engineering Research
- NON-INVASEIVE TESTING FOR OSTEOPOROSIS
- Objective To further develop a non-invasive
technique for analyzing and reporting microdamage
in the trabecular bone the region most affected
by osteoporosis. - Motivation The trabecular bone serves as the
shock absorber for human joints. Also, severe
osteoporosis can be extremely painful and costly.
- Method To assess the acoustic emission from the
trabecular bone by simultaneously acquire
acoustic emission and stress/strain data. - The trabeculuar bone specimens used in the
experiment were extracted from bovine femurs.

- Alison, BSME Summer 2008
- Currently at Grad School at Stanford
Undergraduate Research at GT I worked in a
tissue engineering research lab on working
towards building an artificial blood vessel that
could be implemented into the human body. The
first part was to understand the tissues that
already exist in the body (in particular,
collagen) and how the tissue grows and remodels
under stress change.

company first.
- Advice to Students
- You dont have to know what you want to do with
the rest of your life when you're 17! - Look into all your options and start out studying
something as broad as you can (for example, I
liked science and math and chose ME). - If you want/need advice on a career choice, don't
be afraid to ask someone to talk about what they
do! You'll be surprised to see how nice people
are if you are kind in return.
