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 flow of electrical power or charge.






2. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






3. Distance between adjacent threads in a screw.






4. Used to start and stop flow in a circuit






5. The result of an experiment






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






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






8. 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






9. To monitor and control a process so that the quality of the output/product improves.






10. 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.






11. A device used to remove contamination from a fluid






12. Absolute temperature scale






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






14. 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






15. The process of creating an object by adding small pieces or layers together to make a final product






16. 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






17. A part of the physical world as described by its thermodynamic properties such as temperature - volume - pressure - concentration - surface tension - and viscosity.






18. An electromagnetically operated switching device.






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

20. A body subjected to a push.






21. 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.






22. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






23. 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.






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

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






26. A toothed wheel whose teeth engage the links of a chain.






27. A part or element of a larger whole






28. The ratio of actual strength to required strength






29. Changes one form of power to another






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






31. Numbers or information describing some characteristic.






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






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






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






35. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

36. A resource that can be replaced when needed






37. Changing one form of energy to another






38. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






39. Used to transport fluid in a circuit






40. The unit of potential difference symbolized as V






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






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






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






44. Amount of difference between a value and the mean.






45. 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.

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






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






48. A subordinate routine; specifically - a sequence of computer instructions for performing a specified task that can be used repeatedly.






49. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






50. The opposition that a device or material offers to the flow of direct current
