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. Listing of a data values along with their corresoponding frequencies.






2. The collection and analysis of numerical data in large quantities






3. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






4. The state when objects are not yet in motion






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






6. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






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






8. 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.

9. Frequency distribution graph






10. Numbers or information describing some characteristic.






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






12. Slender straight pieces of a truss connected by joints.






13. The flow of electrical power or charge.






14. The rate at which work is performed or energy is expended






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






16. An energy source that will never run out






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






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. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






20. The ratio of actual strength to required strength






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






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






23. Conversion of a digital signal to its analog equivalent - such as a voltage.






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






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






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






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






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






29. Categorical data graph percentage






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






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






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






33. Not having fixed limits; unrestricted; broad






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






35. The type of charge an atomic particle has






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






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






38. A resource that cannot be replaced once used






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






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






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






42. Bell- shaped probability distribution






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






44. Frequency distibution graph






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






46. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






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






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






49. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






50. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts
