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






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






3. The path by which a message travels from the sender to receiver.






4. Someone who starts a business.






5. The splitting of the nucleus of an atom.






6. 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.






7. The capacity to do work or exert effort.






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






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






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






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






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






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






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






15. A device that orbits the Earth and receives messages from one location and transmits them to another.






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






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






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






19. 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.






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






21. Energy in motion.






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






23. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






24. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






25. A production system in which products are made one at a time according to customer's specifications.






26. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






27. The act of breaking a particular subject into different parts to achieve clarity of understanding.






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






29. The superimposition of sine waves on electromagnetic carrier waves.






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






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






32. A resource that is entered into a system.






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






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






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






36. The basic framework of a system






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






38. Creating things through the process of planning.






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






40. The formal rules that guide the design process.






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






42. The capacity to do work or exert effort.






43. A popular movement.






44. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






45. The field of knowledge relating to materials as they exists on a molecular or atomic level.






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






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






48. 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.






49. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






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