Principles Of 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. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






2. The net transfer of electric charge (electron movement along a path) per unit of time.






3. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






4. A tool for systematically ranking alternatives according to a set of criteria






5. The production of electricity in conductors with the use of magnets






6. Absolute temperature scale






7. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






8. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






9. The rate at which work is performed or energy is expended






10. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






11. An electromagnetically operated switching device.






12. The connection points of members of a truss






13. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






14. A device for making - breaking - or changing the connections in an electrical circuit.






15. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






16. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






17. The basic unit of electric current adopted under the Systeme International d'Unites






18. A process that changes the size and shape of a material by a combination of force and a shaped form






19. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






20. Frequency distribution graph






21. A solid- state switching device.






22. Distance between adjacent threads in a screw.






23. A statsitical measurement of variability






24. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






25. Conversion of an analog signal to a digital quantity such as binary.






26. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






27. An external force applied to an object.






28. The transfer of energy by electromagnetic waves






29. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






30. The return to the input of a part of the output of a machine - system - or process






31. A person or group for which product or service design efforts are intended.






32. Information encoded in a digital form - which is usually stored in an assigned address of a data memory for later use by the processor.






33. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






34. The fractional increase in a material's length due to stress in tension or thermal expansion






35. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






36. The result of an experiment






37. A plate or bracket for strengthening an angle in framework.






38. A device used to create flow in a hydraulic system.






39. Changes one form of power to another






40. Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance






41. The place at which independent and often unrelated systems meet and act on or communicate with each other.






42. Not having fixed limits; unrestricted; broad






43. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






44. A quantity that has both a magnitude and direction.






45. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






46. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

47. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






48. A negative temperature coefficient - also known as a thermistor - is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature.






49. A device used to spray an oil mist into the stream of a pneumatic system.






50. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.
