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






2. The measure of resistance to heat flow






3. The connection points of members of a truss






4. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






5. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






6. 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.






7. 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.

8. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






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






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






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






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






14. Stages a product goes through from concept and use to eventual withdrawal from the market place.






15. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






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






17. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

18. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






19. 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






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






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






22. A physical quantity that has magnitude only.






23. The use of gas flowing under pressure to transmit power from one location to another.






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






25. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






26. Energy caused by the movement of electrons.






27. Plant materials and animal waste used especially as a source of fuel.






28. A truss that lies in a single plane often used to support roofs and bridges






29. A resource that can be replaced when needed






30. The measure of resistance to heat flow






31. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






32. The ratio of actual strength to required strength






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






34. The type of charge an atomic particle has






35. The square root of the variance.






36. Listing of a data values along with their corresoponding frequencies.






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






38. Amount of difference between a value and the mean.






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






40. The rate of change of velocity with respect to time.






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






42. An air pump that compresses air into a receiver tank.






43. The distance the fluid travels through a system in a given period of time.






44. The value that occurs most frequently






45. A sketch that shows an object's height - width - and depth in a single view.






46. 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.

47. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






48. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






49. Energy derived from sources that do not use up natural resources or harm the environment






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