WHAT’S NEW IN ENGINEERING?
The Large Hadron Collider (LHC) is the world's largest and highestenergy particle accelerator.
17 miles in diameter, 570 ft underground, 10,000
scientists/engineers
On 19 September 2008, the operations were halted due to a serious
fault between two superconducting bending magnets. Due to the
resulting damage, the LHC back online July 2009.
ENGINEERING NEWS
On March 30, 2010, the first planned collisions took
place between two 3.5 TeV beams, which set a new world
record for the highest-energy man-made particle
collisions.

INTRODUCTION TO ENGINEERING
Engineering and engineers exist everywhere
From
buildings to iPods, automobiles to High
Definition Televisions, engineering is an integral
part of our daily lives
Some
critics argue that engineering has made our
society lazy, uncommunicative, and less personal
What
do you think?
DO YOU KNOW ANY ENGINEERS??
These famous people actually studied to be an
engineer:
Neil Armstrong, aeronautical engineering
Claim to fame: First man on the moon, of
course!
THESE FAMOUS PEOPLE ACTUALLY STUDIED TO BE
AN ENGINEER
Jimmy Carter, Mechanical Engineering
39th President of United States

Montel Williams, Naval Engineering
Host of the day-time talk show, The Montel Williams
Show
THESE FAMOUS PEOPLE ACTUALLY STUDIED TO BE
AN ENGINEER
Ellen Ochoa, Electrical Engineering
Native of San Diego, CA. 1st Hispanic woman
in space.
Went to space aboard Discovery in 1993.
THESE FAMOUS PEOPLE ACTUALLY STUDIED TO
BE AN ENGINEER
Ashton Kutcher, Biochemical Engineering
Attended the University of Iowa
Dropped out to pursue modeling (Bad move,
dude!)
WHAT’S THE POINT!?
A couple of points to be made
Engineering
is a wide field of study with lots
of options
With hard work and persistence, ANYBODY
can become an engineer
Engineering provides an excellent starting
point for future careers
Presidents,
astronauts, lawyers, doctors,
business people have started as engineers
Talk show host may be a little far-fetched, but
anything is possible!!
SWITCHING GEARS (NO PUN INTENDED)
Let’s talk about how engineering is relevant to our
daily lives
A great source of engineering information that is readily
accessible is the news
Engineering disasters, new technological gadgets, new
buildings are all newsworthy because they cost on the
order of millions of dollars
Much of the money for new building projects and
disaster repair in our state comes from taxpayer dollars.
ENGINEERING IN THE NEWS
2008 Summer Olympic Games (Beijing, China)
Advances in pool design and swimsuit technology have contributed to
the increases in speed for swimmers.
The corset-like Speedo LZR Racer suit is made by ultrasonic welding
instead of stitching and can require a half-hour to put on and shoehorns
the body into a more streamlined position
The Beijing pool eliminates wave action against swimmers by being
deeper, wider, and uses a sophisticated outside lane buffer system.

ENGINEERING HIGHLIGHTS
(…AND LOWLIGHTS)
The iPhone has arrived!! (8GB Retail price = $599)
ENGINEERING HIGHLIGHTS
(…AND LOWLIGHTS)
The iPhone gets hacked by teenager!!
A New Jersey teenager has figured out how to make
Apple's iPhone available on other wireless services
besides AT&T, removing a major frustration for thousands
of consumers.
George Hotz, SUPERBAD!!
ENGINEERING LOWLIGHTS
The Interstate-35 bridge in Minneapolis, Minnesota
collapses. Official death toll is 13 with over 100
injured.
ENGINEERING LOWLIGHTS
U.S. highway bridges are, on average, 40 years
old. The typical interstate bridge was built in the
late 1960s (the I-35 bridge was finished in
1967).
Most bridges are inspected and rated every two
years.
In 2005, engineers rated the I-35 bridge in
Minnesota as "structurally deficient" and
possibly in need of replacement.
Overall, about 20 percent of interstate bridges
(nearly 12,000 bridges) were rated as deficient
in one way or another in 2004.
ENGINEERING HIGHLIGHTS
The $100 laptop: for use in developing
countries
Engineers scaled down the common laptop and
focused on features that developing nations need
(internet, word processing, video call)
YEAH…SO WHAT…WHAT’S THE POINT?
If everything worked perfectly, we wouldn’t
need engineers
Engineering is mainly about improving current
designs and functions to make things more
efficient, useful, cheaper, and safer.

INTRODUCTION TO ENGINEERING MAJORS
What do engineers do?
Invent,
design, develop, manufacture, test, sell, and
service products AND services
Engineering defined:
Profession
in which mathematics and natural
sciences gained by study & experience are needed
to utilize materials and forces of nature for the
benefit of humankind
ENGINEERING DESIGN & ANALYSIS
Engineering design:
A
process of devising a component, system or
operation that meets a specific need
Engineering analysis:
The
analytical solution of an engineering problem,
using mathematics and principles of science.
Failure is a part of engineering!!
