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






2. A part of the physical world as described by its thermodynamic properties such as temperature - volume - pressure - concentration - surface tension - and viscosity.






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






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






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






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






7. A physical quantity that has magnitude only.






8. A support that prevents translation in any direction






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






10. 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.






11. A vector quantity that includes the speed and direction of an object.






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






13. A device that responds to a physical stimulus






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






15. A sketch that shows an object's height - width - and depth in a single view.






16. A part or element of a larger whole






17. Change in length of an object in some direction per unit






18. The distance the fluid travels through a system in a given period of time.






19. The measure of resistance to heat flow






20. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






21. Maximum stress that a material will withstand without permanent deformation






22. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






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






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






25. Any device that controls - either automatically or manually - the flow of a fluid.






26. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

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






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






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






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






38. Values that represent a measurable quantity






39. 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

41. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






42. A body subjected to a push.






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






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