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






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






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






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. A set of all possible outcomes or events in an experiment that cannot be further broken down.






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






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






8. The contact of a relay that is closed when the coil is de- energized.






9. The resistance that one surface or object encounters when moving over another.






10. The transfer of energy by electromagnetic waves






11. Used to transport fluid in a circuit






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






13. The stress required to fracture a material whether by compression - tension - or shear






14. A gear positioned between the driver and the driven gear used to change rotational direction.






15. Frequency distibution graph






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






17. 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.






18. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






19. 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.

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






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






22. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






23. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






24. 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






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






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






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






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

29. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






31. Categorical data graph






32. 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.






33. 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.






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






35. A body subjected to pull.






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






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






38. The reason for which something is done or for which something exists.






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






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






41. A general agreement






42. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






43. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






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






45. The measure of resistance to heat flow






46. A device used to measure flow rate.






47. Maximum stress that a material will withstand without permanent deformation






48. The difference between samples






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






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