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






2. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






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






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






5. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






6. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






7. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






8. 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






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






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






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






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






13. The result of an experiment






14. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






15. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






16. A body subjected to a push.






17. A resource that cannot be replaced once used






18. The contact of a relay that is closed when the coil is de- energized.






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






20. Bell- shaped probability distribution






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






22. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






23. Values that possess names or labels






24. The law stating that the stress of a solid is directly proportional to the strain applied to it


25. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.


26. 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






27. 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.






28. A result of a force moving an object a certain distance






29. The production of electricity in conductors with the use of magnets






30. Numbers or information describing some characteristic.






31. Categorical data graph percentage






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






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






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






35. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant


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






37. Values that represent a measurable quantity






38. A device that holds the compressed air in a pneumatic system.






39. An electromagnetically operated switching device.






40. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






41. A truss that lies in a single plane often used to support roofs and bridges






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






43. The magnitude of the total distance traveled divided by the time elapsed.






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






45. The fractional increase in a material's length due to stress in tension or thermal expansion






46. The collection - evaluation - and interpretation of data






47. A switch that can provide variable motion control






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






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






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