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






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






3. 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.






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






5. Stored energy or energy at rest.






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






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






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






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






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






11. A popular movement.






12. The formal rules that guide the design process.






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






14. 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.






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






16. The use of force to act on an object in order to move move the object in the same direction as the force.






17. 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.






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


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






20. The splitting of the nucleus of an atom.






21. 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.






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






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






24. The capacity to do work or exert effort.






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






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






27. Creating things through the process of planning.






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






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






30. Energy in motion.






31. The judgement of the end result based upon given criteria.






32. A method of obtaining energy from waste products






33. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






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






35. 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.






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






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






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






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






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






41. A resource that is entered into a system.






42. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






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






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






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






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






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






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






49. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






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