ENGR 101 Professor Martinez INTRODUCTION TO SCIENCE, ENGINEERING, AND TECHNOLOGY: LECTURE #1 INTRODUCTIONS Course Syllabus Student introductions: Name, Anticipated Major, University Plans? 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. LHC Rappin’ ENGINEERING NEWS Airliner Lands in Hudson River, NY Extreme Engine Testing Birds Meet Jet Engine Engine Explosion ENGINEERING INNOVATION The circular saw pizza cutter The Beer Thrower YouTube 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 THESE FAMOUS PEOPLE ACTUALLY STUDIED TO BE AN ENGINEER Last Supper Mona Lisa Flying Machine Leonardo Da Vinci, Mechanical Engineering Painted the Mona Lisa and The Last Supper Designed a flying machine THESE FAMOUS PEOPLE ACTUALLY STUDIED TO BE AN ENGINEER 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. EARTHQUAKES EARTHQUAKES EARTHQUAKES 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. OTHER ENGINEERING IN THE NEWS Toyota recall Earthquake in Haiti Mars Land Rover stuck on Mars The Ipad 3D TV 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!! READING HW Please read Chapter 2 for next Monday, 8/30/10 ENGINEERING RESEARCH LAB Grab a laptop and get online Find three(3) different engineering articles that interest you and briefly summarize them in no more than 50 words each. Be prepared to share one summary with the entire class.
