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






2. Values that possess names or labels






3. The resultant of a system of force is the vector sum of all forces.






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






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






6. An energy source that will never run out






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






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






9. 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.

10. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






11. Individual fuel cells that are combined in series.






12. 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.






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






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






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






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






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






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






19. A measure of how easily a material can be twisted






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






21. The amount or quantity of something






22. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






23. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






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






25. A profession for which one trains and which is undertaken as a permanent calling.






26. The use of gas flowing under pressure to transmit power from one location to another.






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






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






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






30. A statsitical measurement of variability






31. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






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






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






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






35. A process that changes the size and shape of a material by a combination of force and a shaped form






36. A control system that considers the output of a system and makes adjustments based on that output.






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






38. Frequency distibution graph






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






40. The total pressure exerted on a system - including atmospheric pressure.






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






42. The ratio of the magnitude of the resistance and effort forces applied a system.






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






44. A body subjected to pull.






45. A device that responds to a physical stimulus






46. The measure of resistance to heat flow






47. A straight line that comes closest to the points on a scatter plot






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






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






50. The information produced by a computer
