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. The contact of a relay that is closed when the coil is de- energized.






2. A result of a force moving an object a certain distance






3. Bell- shaped probability distribution






4. Degree of conformity of a measure to a standard value.






5. Values that represent a measurable quantity






6. A resource that can be replaced when needed






7. Used to control which path fluid takes in a circuit.






8. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






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






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






11. Conversion of a digital signal to its analog equivalent - such as a voltage.






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






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






14. The use of heat from within the Earth or from the atmosphere near oceans






15. 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






16. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






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






18. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






19. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






20. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

21. An activity with observable results






22. The condition of a string - wire - or rod that is stretched between two points






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






24. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






25. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






26. The ratio of actual strength to required strength






27. A law that states all natural processes proceed in a preferred direction






28. A switching device that uses the magnetic field generated by an electrical current for actuation.






29. A support that only prevents a beam from translating in one direction.






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






31. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






32. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






33. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






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






35. The magnitude of the total distance traveled divided by the time elapsed.






36. A small circuit board that controls all the processing within a computer.






37. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






38. The rotating member of an electrical machine






39. A subset of a sample space






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. A quantity that has both a magnitude and direction.






42. A type of system that uses circulating pumps and fans to collect and distribute heat.






43. The volume of fluid that moves through a system in a given period of time.






44. 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.






45. Change in length of an object in some direction per unit






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






47. Energy which a body possesses by virtue of being in motion






48. The tank that holds the fluid in a hydraulic system.






49. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






50. 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
