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 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.






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






3. Two different sized circular objects that are attached together and turn as one.






4. The total pressure exerted on a system - including atmospheric pressure.






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






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






7. A device used to remove contamination from a fluid






8. A control circuit in which the system output has no effect on the control






9. The measurement of how difficult it is for charges to flow through a material






10. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






11. The calculated likelihood that a given event will occur






12. The process of creating an object by adding small pieces or layers together to make a final product






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






14. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






15. A resource that cannot be replaced once used






16. 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.






17. The ratio of actual strength to required strength






18. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






20. A written plan that identifies a problem to be solved - its criteria - and its constraints.






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






22. A systemized body of laws; a set of principles - as of ethics






23. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






24. A measure of a fluid's thickness or resistance to flow.






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






26. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






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






28. The square root of the variance.






29. A body subjected to pull.






30. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






31. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






32. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






33. An energy source that will never run out






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






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






36. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






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






38. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






39. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






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 device used to create flow in a hydraulic system.






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






43. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

44. Changes one form of power to another






45. The use of quality control techniques associated with a process.






46. The information produced by a computer






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






48. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

49. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






50. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms
