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 substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






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






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






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






5. Used to control which path fluid takes in a circuit.






6. 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.






7. The basic unit of electric current adopted under the Systeme International d'Unites






8. A sketch that shows an object's height - width - and depth in a single view.






9. 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






10. Absolute temperature scale






11. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






12. Numbers or information describing some characteristic.






13. 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






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






15. The state when objects are not yet in motion






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






17. 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.






18. Categorical data graph






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






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






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






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






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






25. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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






27. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

28. The transfer of energy by electromagnetic waves






29. The absolute value of a number






30. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






31. A truss that lies in a single plane often used to support roofs and bridges






32. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






33. 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






34. A quantity that has both a magnitude and direction.






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






36. The result of an experiment






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






38. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






39. The calculated likelihood that a given event will occur






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






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






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






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






44. Test methods used to examine an object - material - or system without impairing its future usefulness






45. 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






46. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






47. Measure of variation equal to the sum of the deviations of each value from the mean.






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






49. A group of machined or handmade parts that fit together to form a self- contained unit.






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