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 flow of electrical power or charge.






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






3. The rotating member of an electrical machine






4. The opposition that a device or material offers to the flow of direct current






5. Not having fixed limits; unrestricted; broad






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






7. A dynamo or similar machine for converting mechanical energy into electricity






8. A form of energy that travels through space as waves.






9. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






10. Arithmetic average






11. 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.






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

13. A device used to remove contamination from a fluid






14. The use of quality control techniques associated with a process.






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






16. The condition of a string - wire - or rod that is stretched between two points






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






18. Bell- shaped probability distribution






19. A device that holds the compressed air in a pneumatic system.






20. A person or group for which product or service design efforts are intended.






21. A subordinate routine; specifically - a sequence of computer instructions for performing a specified task that can be used repeatedly.






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






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






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






25. The difference between the maximum and minimum dimensions allowed within the design of a product.






26. 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.

27. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






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






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






30. The production of electricity in conductors with the use of magnets






31. A device used to measure flow rate.






32. Absolute temperature scale






33. Individual fuel cells that are combined in series.






34. A resource that cannot be replaced once used






35. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






36. A circuit in which all parts are connected end to end to provide a single path of current






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






38. The process of creating an object by adding small pieces or layers together to make a final product






39. 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.






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






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






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






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






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






45. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






46. The square root of the variance.






47. 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.

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






49. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






50. Changing one form of energy to another
