  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
