							What Are
Engineers?
Dr Bob Jones
UTPA
Engineers:

  Design new things
  Supervise the making of things
  Manage companies that design and
   make things
  Manage systems that provide things
   (electricity, water, sewer, railroads)
Design

  Find out what is
   needed
  Use science to figure
   out what will work
  Draw/plan the design
Mechanical Engineers

  Design things that
   use energy or
   convert energy
  Motors, turbines
  Machines
  Vehicles (cars,
   airplanes)
Mechanical Engineers
Civil Engineers

    Buildings
    Bridges
    Roads
    Water/Wastewater
    Dams, Reservoirs
    Flood control,
     drainage
Electrical Engineers

  Electronic Devices
   (computers, video
   games, phones, etc)
  Electrically powered
   systems (robots,
   controls)
  Power distribution
   systems (the electric
   company)
Other Engineers

    Chemical           Materials
    Industrial         Metallurgical
    Manufacturing      Plastics
    Petroleum          Marine
    Agricultural
    Systems
    Aerospace
    Biomedical
Electrical Power
Distribution
  Generator is a motor
   in reverse
Different Methods are
used to run generators
  Most plants use fuel
   to make steam and
   turn a turbine
  The turbine turns a
   generator
Primary Fuel Sources
Distribution of power
Transmission
At your house
Floor Plans

  Civil Engineers use
   plans to lay out a
   building.
  You need to draw a
   floor-plan of your
   house
  Notice how doors,
   walls, windows and
   furniture are drawn
Bridges

  Cantilever or Beam
   bridges
  May use trusses or
   frameworks of
   beams and girders
Truss Types
Arch Bridges

  Efficient design
  Works with stone
   and cement
  Roman Aqueducts
Suspension Bridge

  Weight carried by
   cables
