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 value that occurs most frequently






2. A form of energy that travels through space as waves.






3. Individual fuel cells that are combined in series.






4. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






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






6. The collection and analysis of numerical data in large quantities






7. A support that prevents translation and rotation in a beam.






8. The ratio of the magnitude of the resistance and effort forces applied a system.






9. The opposition that a device or material offers to the flow of direct current






10. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






11. 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.






12. Used to start and stop flow in a circuit






13. 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






14. 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






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






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






17. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






18. The fixed point around which a lever rotates.






19. A support that prevents translation in any direction






20. 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






21. 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.






22. A dynamo or similar machine for converting mechanical energy into electricity






23. A toothed wheel whose teeth engage the links of a chain.






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






25. Frequency distibution graph






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






27. Values that represent a measurable quantity






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

29. Information fed into a data processing system or computer.






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






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






32. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






34. The law stating that the stress of a solid is directly proportional to the strain applied to it

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






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






37. Arithmetic average






38. A gear positioned between the driver and the driven gear used to change rotational direction.






39. To monitor and control a process so that the quality of the output/product improves.






40. The total length of path over which the particle travels.






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






42. The measure of resistance to heat flow






43. The ratio of actual strength to required strength






44. The difference between samples






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






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






47. A statsitical measurement of variability






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






49. The force per unit area exerted by a fluid against a surface






50. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant
