Space Shuttle Flip (Click to open clip) The above clip is of the STS-123 Space
Shuttle performing an orbital flip in space.
NASA is extra careful that the thermal tiles underneath the shuttle have not been damaged upon take-off
There are literally thousands of engineering related YouTube clips (maybe millions!)
Who are the first engineers? Why?
What would you consider the first engineering project?
Continue on to find the answers…
Ancient Egyptians (4000-2000 B.C.) Developed systems of math, quarrying,
surveying, construction techniques Stone & metal tools, plow Built large masonry structures (Pyramids,
temples, statues)
People who showed special aptitude in certain areas were identified and assigned to specialized tasks The first real engineers
Construction of Pyramids (2700-2500 B.C.)
Largest masonry structure ever built. WHY? Masonry structures are not as earthquake
resistant than today’s steel framed building Today, bricks/stone are used more for aesthetic
purposes than for structural purposes
58,000,000 tons, 2.3 million limestone blocks
(1 ton = 2,240 lbs.)
The Egyptians made the pyramid with less than a single inch of error
All angles on the pyramid are accurate!
Parthenon (447 B.C.) Made entirely of marble Column ratios in harmony
Roman Aqueduct (312 B.C.) Provided running water and sanitation Major construction using laws of gravity Still exist today in Italy, Spain, and France
The Great Wall of China (220 B.C.) Built to repel Mongolian invaders 3,080 miles long
Longer than the distance from here to New York!! So large you can see the wall from outer space

Leonardo DaVinci Could not read Latin, prevented him from
learning from other scientists. Architect, engineer, sculptor, painter
Johannes Gutenberg Invented the printing press Growing need to spread information
spawned the need for quicker means to copy literature
Borrowed ideas from Chinese method
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 mankind
Aimee Lopez, Civil Engineer
Dilbert
Proficiency and interest in math and science Suggested by high school counselor Relative is an engineer Job prospects High starting salaries
YES & NO!!Ultimately its up to you and your job
satisfaction
Most lucrative college degrees: Nine out of 10 employers see higher competition for qualified engineering graduates, according to a new survey. Why it pays to be a nerd. (Ha-Ha!)

Scientists search for answers Engineers search for answers, but always with
an application in mind. Science is discovery, advancing knowledge. Engineering tackles problems that prevents
product or service (Not maintenance!!) Engineers are not mechanics or maintenance
workers Mechanics/maintenance workers require specialized
classes not normally taught at the university level
Scientist Engineer
Study planets to understand them
Study planets to build spacecraft
Study atomic structure Study atoms to make more efficient microchips
Study neurological system to cure disease
Study system to design artificial limbs
Create new chemicals Mass Produce chemicals
Predict earthquakes Use earthquake data to design safer buildings
What do engineers have to know?
How different factors and disciplines overlap each other
Examples:– Design of an aircraft engine fan blade
Federal Regulations (Noise, Safety, Quality)
– Artificial limb design Biology, Anatomy, Physiology, Mechanical Engineering
– Toothpaste pump production Cost, Productivity Small design changes can save millions of dollars
In the movie, I, Robot, Will Smith has a robotic/bionic arm that looks and moves just like a normal arm. (A robot ripped off his old arm) This is not science fiction, there are
engineers working on how to connect human nerves to robots so that when the brain thinks movement the robot can respond quickly
Imagine if the engineers never took a biology, anatomy or physiology course…(check the next slide to find out!)
Grab a laptop and get online Find three(3) different engineering articles that interest
you and briefly summarize them in no more than 200 words each.
For each summary, include the type of engineering or engineers that the article refers to.
Be prepared to share one summary with the entire class. Turn in your research lab to the professor
