Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






2. A circuit in which electricity flows along more than one path.






3. Standards that a product must meet to be accepted.






4. The capacity to do work or exert effort.






5. The use of 3D CAD drawings to create real models of a product within a sort of time.






6. The act of putting different things together to form a new product or idea.






7. A language - used to write computer programs - that can easily be translated into machine language.






8. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






9. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






10. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






11. The unlawful acquisition of some one's personal information for use without their consent.






12. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


13. A circuit in which electricity flows along a single path to more than one device.






14. The use of pressurized liquid or gasses to control and transmit power.






15. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






16. A method of obtaining energy from waste products






17. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






18. Current flow in which electrons move in only one direction.






19. A group of people working together to accomplish a common goal.






20. The formal rules that guide the design process.






21. The basic framework of a system






22. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






23. Studying the effects of a given technology to determine its impact.






24. A group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






25. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






26. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






27. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






28. The path by which electric current or pulses flow.






29. A unit that collects waves and decodes information contained within those waves.






30. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






31. A resource that is entered into a system.






32. The use of computers in each stage of the design process.






33. The process of turning abstractions of thought into concrete ideas.






34. Someone who starts a business.






35. A production process in which the part or product moves down a line from one station to the next while parts are added.






36. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






37. The money a business makes after all expenses have been paid






38. Trade of products and services on a global scale.






39. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






40. Current flow in which electrons reverse direction at regular intervals.






41. Restriction or limit placed on a product.






42. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






43. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






44. The technology field focused on sending messages and other in formation using different means.






45. The use of a computer system to produce technical drawings and/or design a product.






46. The capacity to do work or exert effort.






47. The use of simple machines to multiply the output force of a mechanical system.






48. The use of lasers to record realistic images of three- dimensional objects.






49. Stored energy or energy at rest.






50. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.
