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






3. A resource that cannot be replaced once used






4. 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.






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






6. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






7. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






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






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






10. A support that prevents translation and rotation in a beam.






11. Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance






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






13. The total length of path over which the particle travels.






14. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






15. Absolute temperature scale






16. A device used to spray an oil mist into the stream of a pneumatic system.






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






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






19. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






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






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






22. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






23. Individual fuel cells that are combined in series.






24. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






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






26. A plate or bracket for strengthening an angle in framework.






27. Used to transport fluid in a circuit






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






29. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






30. The condition of unrestrained motion in a gravitational field.






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






32. A switching device that uses the magnetic field generated by an electrical current for actuation.






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






34. Values that possess names or labels






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






36. The amount or quantity of something






37. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






38. Changes one form of power to another






39. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






40. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






41. The probability of satisfactory operation of the product in a given environment over a specified time interval.






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






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






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

45. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






47. The transfer of energy by electromagnetic waves






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






49. Ratio of distance traveled by the applied effort and resistance force within a system.






50. 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.
