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 ratio of the useful energy delivered by a dynamic system to the energy supplied to it






2. A valve that allows flow in one direction but prevents flow in the opposite direction.






3. A law that states all natural processes proceed in a preferred direction






4. 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

18. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






19. The measure of resistance to heat flow






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






21. Bell- shaped probability distribution






22. A switching device that uses the magnetic field generated by an electrical current for actuation.

24. A statsitical measurement of variability






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






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






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






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






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






30. A group of machined or handmade parts that fit together to form a self- contained unit.






31. A device used to remove contamination from a fluid






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






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






34. Graphical representation of a material's mechanical properties






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






36. A resource that cannot be replaced once used






37. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

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






42. Used to transport fluid in a circuit






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






44. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






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






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






47. The fractional increase in a material's length due to stress in tension or thermal expansion






48. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






49. A body subjected to a push.






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