Engineering Resources Lesson 3-3

1
Engineering ResourcesLesson 3-3

• Core Technologies

2
Purpose

• To familiarize students with the engineering
  resources (core technologies), the building
  blocks of the designed world.
• To identify and describe the core technologies as
  they are applied in the designed world.

3
Engineering Resources

• A technology system is a group of resources
  (subsystems) working together to solve problems
  and extend human capabilities.

4
Engineering Resources

• Mechanical technology
• The technology of putting together mechanical
  parts to produce, control, and transmit motion.
• Examples???
• transmission gears, bicycle brakes, latch on a
  door.

5
Engineering Resources

• Structural Technology
• The technology of putting mechanical parts and
  materials together to create supports,
  containers, shelters, connectors, and functional
  shapes.
• Example???
• legs on a chair, city water tower, roads,
  bridges.

6
Engineering Resources

• Electrical Technology
• The technology of producing, storing,
  controlling, transmitting, and getting work from
  electrical power.
• Example???
• power plant generator, electric can opener, hair
  dryer.

7
Engineering Resources

• Electronic Technology
• The technology of using small amounts of
  electricity for controlling, detecting and
  information collecting, storing, retrieving
  processing and communicating.
• Example???
• thermostat, metal detector, TV

8
Engineering Resources

• Fluid Technology
• The technology of using fluid, either gaseous
  (pneumatics) or liquid (hydraulic) to apply force
  or to transport.
• Example???
• plumbing in your home, air brakes, air in a tire

9
Engineering Resources

• Optical Technology
• The technology of producing light using light
  for information collecting, storing, retrieving,
  processing, and communicating and using light to
  do work.
• Example???
• light-emitting diode, magnifying lens, laser
  cutting tool.

10
Engineering Resources

• Thermal Technology
• The technology of producing, storing, controlling
  transmitting and getting work from heat energy.
• Example???
• toaster, hot water heater, jet engine

11
Engineering Resources

• Biotechnology
• The technology of using, adapting, and altering
  organisms and biological processes for a desired
  outcome.
• Example???
• stain-eating enzymes in detergents, bacteria
  leaching metals from ore, altering plant genes to
  produce better crops.

12
Engineering Resources

• Materials Technology
• The technology of producing, altering, and
  combining materials.
• Example???
• making paper from wood, drilling holes in wood,
  making aluminum foil from ore
