  1. Introduction to Engineering and Technology

  2. What do you Think?

  3. Engineering Is • The essence of engineering is design. • Engineering design entails the application of math, science, and technology to create something that meets a human need. • The engineering design process is, at the same time, systematic and creative. • And the engineering design process is always iterative: engineers must explore many different alternatives before they can hope to achieve an optimum solution. • These are the essential characteristics of engineering.

  4. Engineering I • Define Mathematics. • Define Science. • Define Technology -

  5. Technology • What is Technology? • Construct a definition of Technology • What is an “-ology?” • Sociology, Biology, Psychology • So what is good working definition of the word “Technology”?

  6. Technology • Technology is human knowledge • Technology uses tools, materials, and systems • Application of technology results in artifacts (human-made things) or other outputs (pollution and scrap) • Technology is developed by people to modify or control the environment • Dynamic – floppy disk

  7. Engineering Overview Julie Sonnenberg-Klein Project Director, MaST – Math Science & Technology Initiatives

  8. Part IScience, Engineering, Technology Concepts of Science & Engineering • Scientists determine how the natural world operates • Engineers apply science to make products • Technicians use products, follow procedures

  9. Science, Engineering & Engineering Technology Engineers Technicians Scientists Discover Understand Explain Design Create Operate Maintain

  10.

  12. Engineering I • How old is technology? • Many archaeologists, sociologists believe ONE technology has shaped our society to what it is today. Can you guess what it is? • The plow! • What were the societal effects of this technology? • What innovations were made on it?

  13. Engineering I • Our earliest ancestors had to develop ways to solve problems. • The Cave Man……. Look at our teeth. • 1. This is not an argument about evolution. We make no assumptions about the origin of man. • 2. It is a fact that human teeth differ from that of strict carnivores.

  14. Engineering I • In order to eat we needed to develop tools. • Tools are the first essential element for all technology systems. • These tools are made of materials (2nd) • We name eras according to material usage • Stone Age approx. 2,000,000 years ago. • Bronze Age approx. 3000 BC-alloy using copper and tin • Iron Age approx. 1200 BC • Middle Ages – printed money and Printing Press • Industrial Age • Information Age

  15. Engineering I • Examine a Specific Artifact- Pick one! • What is it made of? • We call these materials resources. • Natural and Man-made. • Renewable, Non-renewable and re-usable. • What were the affects of this technology? • How has “drive-thru” technology altered our society? • SO NOW DEFINE TECHNOLOGY!!

  16. Engineering I • Technology defined: The study of taking resources, applying a process to make things that satisfy our needs. • Similar to the sciences, technology has a unique academic based body of knowledge. • However, how do you think technology differs from “traditional” academic subjects? • Discussion of this definition?

  17. Engineering I • Technology is defined as a system having seven essential elements: • Capital • Energy • Resources/Materials • Tools • People • Information • Time

  18. Engineering I • The powers that be have developed the following definition…live it, love it, LEARN IT! • Technology: The generation of knowledge and processes to develop systems that solve problems and extend human capabilities.

  19. Engineering I • Story time: Scientists have observed monkeys in the South American rainforest. These monkeys eat Brazilia Nuts off trees. The shell is too hard to bite open. These monkeys have found they can use a rock to smash the nut on the ground to open it. • According to our definition is this Technology?

  20. Engineering I • All Technology can be classified into three general classifications: • Information Systems: • Physical Systems: Construction, Transportation, Manufacturing • Bio-related Systems

  21. Engineering I • Technology is a unique academic discipline that borrows knowledge and information from all other academic areas: • Tech and Science (Nuclear energy plants) • Tech and Math (The ½ gallon milk jug problem) • Tech and Language Arts ($$$ Technical writers) • Tech and Social Studies (Social responsibility) • Tech and Foreign Language (Global economy) • Tech and Music (Instruments are tools) • Tech and Visual Arts (Escher)

  22. Engineering I • So now lets examine engineering. • Engineering design entails the application of math, science, and technology to create something that meets a human need. • Human need is central.

  23. Engineering I • Egyptian Engineers • Imhotep: Engineer to King Joser • Engineers to the Kushite Kings • Pyramids, Dams, and Canals • Mesopotamian Engineers • First Canals built by the Sumerians of Southern Mesopotamia • Home and Wall construction • Assyrians and iron weaponry and the four wheeled war machine/wagons • Aqueducts and paved streets of King Engineer Sennacherib • Greek Engineers • Borrowed concepts of construction from Assyrians and Mesopotamians • 1st Metal Structure is attributed to the Greeks. • Golden age engineer Archytas of Taras, pure scientist and engineer. • Mechanical Bird that flew by compressed air.

  24. Engineering I • Greek Engineers: • Hellenistic Greeks were a mixture of Greek and Oriental people. • Archimedes and the science of hydrostatics was a result of Hellenistic Greek. • Roman Engineers: • Romans were also adaptive engineers; building off others ideas. • Most were civil engineers developing roads, bridges, etc. • Made significant advances in architecture and everyday machinery. • Kingdom of Anatolia Central Indirect Heating • Discovery of Cement! • Use of the waterwheel, trusses and the pendentive.

  25. Engineering I • The Oriental Engineers: • Centered on religious activities. • Indian – Skills with iron works • Arabic – Skills with water clocks and waterwheels and the first practical windmill. • Chinese – Suspension and cable stayed bridges, canals and dams. • The European Engineers: • Middle Ages was the height of invention. • Advances in cathedrals..the flying buttress • 18th century advanced hydraulics, canal building. • Renaissance saw the advent of engineering schools and engineering became a defined discipline.

  26. Discussion Has your idea of the field of engineering changed now that we have discussed it? If yes, how?

  27. Careers in Engineering • ABET – The Accreditation Board for Engineering and Technology. • Engineering defined as: • The profession which the knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied with judgment to develop ways to use, economically, the materials and forces of nature for the benefit of mankind. • Using materials and forces for the good of humankind.

  28. Careers in Engineering • Discipline: A specific area practiced by an engineer. • They do overlap. • There are several sub-categories under each of the major headings. • Role: The jobs within the disciplines that are held by engineers. • Research, Inventor, Supervisor, Human Resources, Sales, Financial Management • Example: Degreed Mechanical Engineer that is the head of Sales for Ford Motor Corporation.
