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. Changing one form of energy to another






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






3. A device used to spray an oil mist into the stream of a pneumatic system.






4. A set of all possible outcomes or events in an experiment that cannot be further broken down.






5. 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.






6. An activity with observable results






7. A physical quantity that has magnitude only.






8. A device used to remove contamination from a fluid






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






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






11. Categorical data graph






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






13. 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






14. The type of charge an atomic particle has






15. A device used to measure flow rate.






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






17. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






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






19. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






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






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






22. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






23. A device for making - breaking - or changing the connections in an electrical circuit.






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






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






26. Energy caused by the movement of electrons.






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






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






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






30. A profession for which one trains and which is undertaken as a permanent calling.






31. Distance between adjacent threads in a screw.






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






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






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






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






36. Changes one form of power to another






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






38. The state when objects are not yet in motion






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






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

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






42. A subordinate routine; specifically - a sequence of computer instructions for performing a specified task that can be used repeatedly.






43. The unit of potential difference symbolized as V






44. A statsitical measurement of variability






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






46. The geometric center of an area.






47. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






48. A surface or shape exposed by making a straight cut through something at right angles to the axis.






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






50. The transfer of energy by electromagnetic waves
