1. Unit 2 Lesson 3 Technology Systems

2. Big IDEA Big Idea: There are nine “Core Technologies” that are fundamental to all technology systems that must be recognized and understood.

3. mechanical systems A mechanical system manages power to accomplish a task that involves forces and movement Steam Engine

4. structural systems The term structural system transfers loads through interconnected structural components or members. Example a Truss Bridge

5. fluid systems system that uses the force of flowing liquids and gases to transmit power. Fluid systems include hydraulic systems and pneumatic systems. force. The push or pull that changes an object's state of motion. gas.

6. optical systems a combination of lenses, mirrors, and prisms that constitutes the optical part of an optical instrument (as a microscope or telescope)

7. electrical systems A system that provides electricity Light Switch Car Dash and Lights

8. electronic systems Electronic systems are groupings of electronic circuits and components which are designed to accomplish one or more complex functions. Examples include telecommunication systems, computer systems, power distribution systems, radar systems, electronic music systems, and many others.

9. thermal systems A thermal system is a multipart assembly of coupled components (some of them thermal), showing a common structured behavior; e.g. a refrigerator is a combination of pipes, compressor, electric motor, heat exchangers, valves, insulation, casing, doors, lamp, etc., interacting to a common goal of cold production within. Therefore, a refrigerator is a thermal system, whereas the refrigerant fluid and the interior space are thermodynamic systems.

10. bio-technical systems is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity, Art. 2).

11. material systems The combining of materials to make new things
