Engineering – A Team Sport
Evan Lemley, UCO Phys. And Engr.August 24, 2004
ENGR 1111 Introduction to Engineering
University of Central Oklahoma
Organization
• What is Engineering?• What is an Engineering Team?• Who should be an Engineer and
Why?• Engineering Disciplines.• How to become an Engineer.
What is Engineering? Compare and Contrast
• Engineering– Learn Math and
Physics– Apply math and
physics to build new devices
– Design of applications that solve a given problem is the emphasis
• Physics– Learn Math and
Physics– Apply math and
physics to understand workings of universe
– Design of experiments that help understand workings of universe is the emphasis
What is Engineering?
• Def.: Use of technology to solve problems– Industrial – apply science and math to solve
manufacturing problems– Consulting – apply science and math to design
things from scratch or assess existing designs– Research and Development – apply newer
science and math to create new products and devices
– Academic Research – Apply science and math to previously unsolved problems (short term significance may not quite exist)
• Help discover new science
What is an Engineering Team?
• Many problems are solved by teams– Scientists – Generalists, Design, Is there any
thing we forgot?– Engineers – Design and Analyze– Technicians – Build, Test, and Debug
• Engineering and other work is moving more this direction.
• Engineering degree programs are more focused this direction… labs and design projects
Cold Fusion – Univ. of Utah Early 1990’s
• What: “Table-Top” fusion… really big deal• Who: Drs. Pons and Fleishman• Who else: Team from of Los Alamos• Why: Is it real• How: Neutron and other detectors• What happened: NO NEUTRONS OR
ANYTHING ELSE• What kind of Engineers?
Columbia Disaster - 2003
• Large Team of Scientists, Engineers, and Technicians
• Government – NASA, Industry –Contractors, Independent Board (CAIB)
• CAIB – Columbia Accident Investigation Board (www.caib.us)
• Cause: Foam insulation hits Leading Edge? – Southwest Research Institute
Air Gun
Target
Foam Impact
Is Engineering For You?
• Do you like to take things apart and put them back together? (understanding how things work)
• Do you like solving difficult problems?• Are you interested in Science and Math?• Do you like working with other technical
people?
Why Become an Engineer? - ASEE
• Job Satisfaction• Variety of Career Opportunities• Challenging Work• Intellectual Development• Potential to Benefit Society• Financial Security• Prestige• Professional Environment• Technological and Scientific Discovery• Creative Thinking
Why Become an Engineer? - Lemley
• Fame -probably not• Money -a few rich engineers• Security – pretty secure• Good at it and like it• Idealistic – contribute in a positive
way to use of technology
Science and MathRequirements
• Physics – cornerstone of technology• Chemistry• Biology• Materials – microscopic details of how materials fit
together and how they respond to outside forces Math – Engineering is applied mathematics– Algebra, Trig, Calculus, Differential Equations,
Linear Algebra• Computers – running software, spreadsheets,
word-processing, writing programs, CAD, ProE, specific engineering software
Aeronautical Engineering
• Aerodynamics, Fluid Mechanics• Design and build aircraft,
spacecraft, land vehicles• Big companies with large-scale
projects
Agricultural Engineering
• Hydrology, Soil Mechanics, Biology• Produce food on a large scale
Engineering DisciplinesBiomedical Engineering
• Modern engineering methods to solve problems in medicine and human health.
• Health and medical-related industries
• High growth rate
Chemical Engineering
• Chemistry to design and manufacture production systems where chemical reactions are involved
• Chemistry, fluid mechanics, heat transfer
• Petroleum, chemical, plastics, electronics (small – large scale)
Civil Engineering
• Design and construction of roads, bridges, and other large structures
• Wastewater, water supply, erosion, environmental engineering
• Government, large construction, and consulting firms
Computer Engineering
• Hardware, software, and digital communication
• Formerly part of electrical engineering
• Small – Large Scale Employment
Electrical Engineering
• Use and control of electromagnetic energy
• Microelectronics to power distribution, data communication, fiber optics, power systems, microprocessor design
Engineering Physics
• Engineering + Physics = EP• Good Engineering Problem Solvers that
know the background physics very well• Job Options
– Engineer, physicist, software engineer, Graduate School (physics or engineering)
• Curriculum = Standard Physics + Basic Engineering Science Courses
Industrial Engineering
• Design of devices and systems for mass production and manufacturing facilities
• Heavy-duty statistics• Industrial Manufacturing
employment
Mechanical Engineering
• Designing and building physical structures
• Mechanical Design -- Machines• Fluid/Thermal Design
– HVAC– Industrial Processes
• Very wide employability
Mechatronics Engineering
• Mechanical engineering plus electronics plus computers
• Solve problems that a mechanical or electrical engineer could not solve alone
Naval Engineering
• Design of ships, subs, and other sea-going vessels
• Oil platforms• Government and private sector
Nuclear Engineering
• Design of systems that involve nuclear reactions
• Reactor engineer, radiation protection
• Strong ties to mechanical and to physics
• Engineering Physics majors are good nuclear engineers
Other Engineering
• Petroleum Engineering– Production of oil and gas from resources
• Systems Engineering– Design, implementation, and control of
large-scale systems (computer, utilities, governments)
– Data processing, power generation, transmission, communications, aerospace
How to Become an Engineer
• Bachelor’s Degree Required• Engineering vs. Engr. Tech.• Engineering Core 1.5 years• Math and Physics – 1 year• Engineering Physics – more physics• Some projects need a “licensed” engineer
– Esp. when public use and safety are involved– Approve Design– Some Legal Responsibility
How to Become an Engineer
• Licensed Engineers are P.E.s– Professional Engineers
– Process to be Licensed• Fundamentals of Engineering Exam (FE)
– Senior year, General and Specific Sections
• Engineering Intern Period (at least four years of engineering practice)
• Prof. Engr. Exam (in chosen area)
– Not necessary for many engineers
– Helpful to be eligible for PE (pass the FE Exam)
