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. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

2. An electromagnetically operated switching device.






3. A device used to remove contamination from a fluid






4. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






5. The tank that holds the fluid in a hydraulic system.






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






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






8. A subset of a sample space






9. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






10. A device used to measure flow rate.






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






12. Individual fuel cells that are combined in series.






13. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






14. A part or element of a larger whole






15. The connection points of members of a truss






16. A device that responds to a physical stimulus






17. Numbers or information describing some characteristic.






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






19. Changes one form of power to another






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






21. The collection - evaluation - and interpretation of data






22. A surface or shape exposed by making a straight cut through something at right angles to the axis.






23. The difference between samples






24. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






25. Degree of conformity of a measure to a standard value.






26. 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.






27. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






28. Anything for which a person is legally bound or responsible






29. A body subjected to a push.






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






31. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






32. Information encoded in a digital form - which is usually stored in an assigned address of a data memory for later use by the processor.






33. Arithmetic average






34. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






35. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






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






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






38. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






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






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






41. The use of gas flowing under pressure to transmit power from one location to another.






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






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






44. 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.






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






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






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






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






49. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






50. A resource that can be replaced when needed
