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






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






3. Individual fuel cells that are combined in series.






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






5. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






6. 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






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






8. 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






9. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






10. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






11. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






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






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






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






15. Not having fixed limits; unrestricted; broad






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






17. 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.






18. The measure of resistance to heat flow






19. The stress required to fracture a material whether by compression - tension - or shear






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






21. A statsitical measurement of variability






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






23. 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






24. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






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






26. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






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






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






29. The fixed point around which a lever rotates.






30. Values that represent a measurable quantity






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






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






33. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






34. The geometric center of an area.






35. The value that occurs most frequently






36. A measure of how easily a material can be twisted






37. A switch that can provide variable motion control






38. 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.






39. The square root of the variance.






40. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






41. 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.






42. An external force applied to an object.






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






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






45. Bell- shaped probability distribution






46. A subset of a sample space






47. The information produced by a computer






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






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






50. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.
