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. An electromagnetically operated switching device.






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






3. A written plan that identifies a problem to be solved - its criteria - and its constraints.






4. Middle value of a set of values arranged in order of magnitude.






5. A resource that cannot be replaced once used






6. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






7. The connection points of members of a truss






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






9. The fractional increase in a material's length due to stress in tension or thermal expansion






10. Changes one form of power to another






11. A process that changes the size and shape of a material by a combination of force and a shaped form






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






13. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






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






15. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






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






17. The probability of an event occurring based upon other event probabilities

18. The ratio of the magnitude of the resistance and effort forces applied a system.






19. 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






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






21. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






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






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






24. Distance between adjacent threads in a screw.






25. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






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






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

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






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






30. A solid- state switching device.






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






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






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






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






35. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






36. A system that links electricity produced in power stations to deliver it to where it is needed






37. An inclined plane wrapped around a cylinder - forming the path and pitch.






38. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






40. The value that occurs most frequently






41. 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.






42. 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.






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






44. The geometric center of an area.






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






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






47. 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






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






49. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






50. A small circuit board that controls all the processing within a computer.
