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






2. Distance between adjacent threads in a screw.






3. The contact of a relay that is open when the coil is de- energized






4. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






5. The state when objects are not yet in motion






6. Not having fixed limits; unrestricted; broad






7. 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.






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






9. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






10. The condition or quality of being true - correct - or exact; precision; exactness.






11. A physical quantity that has magnitude only.






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






13. A subset of a sample space






14. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

16. A body subjected to pull.






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






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






19. A force that produces or tends to produce rotation or torsion.






20. 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






21. 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






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






23. The use of heat from within the Earth or from the atmosphere near oceans






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

25. A device used to measure flow rate.






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






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






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






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






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






31. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






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






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






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






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






36. A type of system that uses circulating pumps and fans to collect and distribute heat.






37. Frequency distribution graph






38. A form of energy that travels through space as waves.






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






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






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






42. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

43. A dynamo or similar machine for converting mechanical energy into electricity






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






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






46. 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.






47. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






48. A support that prevents translation in any direction






49. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






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