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. Energy caused by the movement of electrons.






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






3. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






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






5. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat






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






7. The collection - evaluation - and interpretation of data






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






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






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






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






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






13. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant


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






15. A type of system that uses circulating pumps and fans to collect and distribute heat.






16. 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.






17. 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.






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






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






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






21. Values that represent a measurable quantity






22. The connection points of members of a truss






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






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






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






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






27. Individual fuel cells that are combined in series.






28. Any alteration of shape or dimensions of a body caused by stresses - thermal expansion or contraction - chemical or metallurgical transformations - or shrinkage and expansions due to moisture change






29. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






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






31. A toothed wheel whose teeth engage the links of a chain.






32. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






33. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






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






36. Changes one form of power to another






37. The ratio of actual strength to required strength






38. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.


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






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


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






42. The state when objects are not yet in motion






43. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






44. Energy which a body possesses by virtue of being in motion






45. The basic unit of electric current adopted under the Systeme International d'Unites






46. A solid- state switching device.






47. The rate at which work is performed or energy is expended






48. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






49. A support that only prevents a beam from translating in one direction.






50. A device used to measure flow rate.
