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






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






3. A switch that can provide variable motion control






4. A subset of a sample space






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






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






7. The measure of resistance to heat flow






8. Categorical data graph percentage






9. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






10. The absolute value of a number






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






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






13. The square root of the variance.






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






15. Information fed into a data processing system or computer.






16. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






17. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






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






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






20. The probability of satisfactory operation of the product in a given environment over a specified time interval.






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






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






23. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






24. The state when objects are not yet in motion






25. The use of a fluid (liquid or gas) to transmit power from one location to another.






26. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






27. The measurement of how difficult it is for charges to flow through a material






28. Individual fuel cells that are combined in series.






29. The amount or quantity of something






30. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






31. Values that possess names or labels






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






33. Energy derived from sources that do not use up natural resources or harm the environment






34. A truss composed of triangles - which will retain its shape even when removed from supports.






35. Graphical representation of a material's mechanical properties






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






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






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






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






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






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






42. Two different sized circular objects that are attached together and turn as one.






43. The calculated likelihood that a given event will occur






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






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






46. 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.

47. 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
