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






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






3. 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






4. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






5. The calculated likelihood that a given event will occur






6. The condition or quality of being true - correct - or exact; precision; exactness.






7. 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






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






9. A support that prevents translation in any direction






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






11. Categorical data graph






12. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






13. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






14. The law stating that the stress of a solid is directly proportional to the strain applied to it

15. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






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






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






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






19. The information produced by a computer






20. The use of a liquid flowing under pressure to transmit power from one location to another






21. An energy source that will never run out






22. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






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






24. A part or element of a larger whole






25. Numbers or information describing some characteristic.






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






27. The geometric center of an area.






28. A profession for which one trains and which is undertaken as a permanent calling.






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






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






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






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






33. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






34. Individual fuel cells that are combined in series.






35. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






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






37. 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






38. Used to transport fluid in a circuit






39. 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.

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






41. Used to start and stop flow in a circuit






42. The magnitude of the total distance traveled divided by the time elapsed.






43. 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






44. Stages a product goes through from concept and use to eventual withdrawal from the market place.






45. Measure of data scatter






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






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






48. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






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






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