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. Arithmetic average






2. The square root of the variance.






3. Middle value of a set of values arranged in order of magnitude.






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






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






6. Used to transport fluid in a circuit






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






8. Pressure exerted by a confined fluid acts undiminished equally in all directions

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






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






11. Graphical representation of a material's mechanical properties






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






13. The unit of potential difference symbolized as V






14. The transfer of energy by electromagnetic waves






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






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






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






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






19. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






20. The probability of satisfactory operation of the product in a given environment over a specified time interval.






21. The result of an experiment






22. Categorical data graph percentage






23. The place at which independent and often unrelated systems meet and act on or communicate with each other.






24. Changes one form of power to another






25. The use of a liquid flowing under pressure to transmit power from one location to another






26. Bell- shaped probability distribution






27. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






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






29. Distance between adjacent threads in a screw.






30. The probability of an event occurring based upon other event probabilities

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






32. 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






33. A statsitical measurement of variability






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






35. The calculated likelihood that a given event will occur






36. Anything for which a person is legally bound or responsible






37. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






38. Impeding effect exerted by one material object on another.






39. A device that responds to a physical stimulus






40. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






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






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






43. A solid- state switching device.






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






45. An activity with observable results






46. The use of a fluid (liquid or gas) to transmit power from one location to another.






47. Frequency distribution graph






48. 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






49. A device used to convert fluid power into mechanical power in the form of linear motion.






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