Title: Introduction to Engineering


1
Introduction to Engineering
2
Engineering I
  • Engineers build bridges.
  • Engineers test structures by loading them to
    failure.
  • Engineers design bridges for maximum strength-to
    weight ratio.
  • Unfortunately, all three of these notions are
    quite wrong.

3
Engineering I
  • 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, both 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
Engineering I
  • 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
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?

7
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.

8
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
  • Iron Age approx. 1200 BC

9
Engineering I
  • As discussed the Plow came about in 8,000 BC
  • Importance of Agricultural Based tools
  • Plow, Carts, Carriages, Water Wheels.
  • The waterwheel was invented around 100BC. It was
    used primarily to grind grain for food.

10
Engineering I
  • Adaptations today resemble turbines spun by the
    flow of water through a sluice in a dam.
  • Additional gears and fly wheels were set up to
    the original waterwheels to spin milling
    equipment for lumber.
  • Man adapted his tools to satisfy needs.
  • Can you see the changes these technologies made
    in the way man lived?

11
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!!

12
Engineering I
  • Resources
  • Observations of our Environment (I.e., Laws of
    Physics, etc.)
  • Applied a process
  • Fashioned something (an Artifact)
  • To satisfy our needs

13
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?

14
Engineering I
  • Technology is defined as a system having seven
    essential elements
  • Capital
  • Energy
  • Resources/Materials
  • Tools
  • People
  • Information
  • Time

15
Engineering I
  • The powers that be have developed the following
    definitionlive it, love it, LEARN IT!
  • Technology The generation of knowledge and
    processes to develop systems that solve problems
    and extend human capabilities.

16
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?

17
Engineering I
  • All Technology can be classified into five
    general classifications
  • Construction
  • Transportation
  • Manufacturing
  • Communication
  • Bio-related

18
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)

19
Engineering I
  • So know 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.

20
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.

21
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.

22
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.

    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.

23
Engineering I
  • Engineering design entails the application of
    math, science, and technology to create something
    that meets a human need.
  • Similar to Technology definition.

24
