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 group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






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






3. 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.






4. The ratio of actual strength to required strength






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






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






7. A support that prevents translation in any direction






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






9. The difference between the maximum and minimum dimensions allowed within the design of a product.






10. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






11. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat






12. Any device that controls - either automatically or manually - the flow of a fluid.






13. 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






14. Pressure exerted by a confined fluid acts undiminished equally in all directions


15. A device used to measure flow rate.






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






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






18. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant


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






20. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






21. The force per unit area exerted by a fluid against a surface






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






23. A physical quantity that has magnitude only.






24. A vector quantity that includes the speed and direction of an object.






25. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






26. 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






27. An inclined plane wrapped around a cylinder - forming the path and pitch.






28. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






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






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






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






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






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






34. A device used to remove contamination from a fluid






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






36. A resource that can be replaced when needed






37. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






38. A system of discrete states: high or low - on or off - 1 or 0.






39. Energy which a body possesses by virtue of being in motion






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






41. A valve that allows flow in one direction but prevents flow in the opposite direction.






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






43. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






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






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






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






47. 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






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






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






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