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 device used to measure flow rate.






2. Used to transport fluid in a circuit






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






4. A system of discrete states: high or low - on or off - 1 or 0.






5. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






6. Distance between adjacent threads in a screw.






7. A body subjected to pull.






8. A vector quantity that includes the speed and direction of an object.






9. 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.






10. The transfer of energy by electromagnetic waves






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






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






13. The value that occurs most frequently






14. A system that links electricity produced in power stations to deliver it to where it is needed






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






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






17. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






18. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






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






20. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






21. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






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






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






24. Test methods used to examine an object - material - or system without impairing its future usefulness






25. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






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






27. The square root of the variance.






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






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






30. Individual fuel cells that are combined in series.






31. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

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






33. Energy caused by the movement of electrons.






34. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






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






36. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






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






38. A part or element of a larger whole






39. A subset of a sample space






40. The connection points of members of a truss






41. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






42. Ratio of distance traveled by the applied effort and resistance force within a system.






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






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

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






46. 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






47. The calculated likelihood that a given event will occur






48. A device that holds the compressed air in a pneumatic system.






49. The condition or quality of being true - correct - or exact; precision; exactness.






50. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.
