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






2. The absolute value of a number






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






4. Values that represent a measurable quantity






5. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






6. 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.






7. 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






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






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






10. Categorical data graph percentage






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






12. A resource that can be replaced when needed






13. The measure of resistance to heat flow






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






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






16. A switch that can provide variable motion control






17. The collection - evaluation - and interpretation of data






18. A truss that lies in a single plane often used to support roofs and bridges






19. A control circuit in which the system output has no effect on the control






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






21. The volume of fluid that moves through a system in a given period of time.






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

23. Used to start and stop flow in a circuit






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






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






26. Distance between adjacent threads in a screw.






27. An electromagnetically operated switching device.






28. An activity with observable results






29. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






30. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






32. A straight line that comes closest to the points on a scatter plot






33. 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.






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






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






36. Frequency distribution graph






37. 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






38. A result of a force moving an object a certain distance






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






40. The transfer of energy by electromagnetic waves






41. Not having fixed limits; unrestricted; broad






42. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






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






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






45. A device used to measure flow rate.






46. The difference between samples






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






48. Energy caused by the movement of electrons.






49. Slender straight pieces of a truss connected by joints.






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