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. Ratio of distance traveled by the applied effort and resistance force within a system.






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






3. A gear positioned between the driver and the driven gear used to change rotational direction.






4. A tool for systematically ranking alternatives according to a set of criteria






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






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






7. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






8. 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.






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






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






11. The distance the fluid travels through a system in a given period of time.






12. A plate or bracket for strengthening an angle in framework.






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






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






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






16. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

17. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






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






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






20. Measure of data scatter






21. 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






22. A circuit in which all parts are connected end to end to provide a single path of current






23. Degree of conformity of a measure to a standard value.






24. The probability of an event occurring based upon other event probabilities

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






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






27. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






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






29. An energy source that will never run out






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






31. The calculated likelihood that a given event will occur






32. The measure of resistance to heat flow






33. Changing one form of energy to another






34. Maximum stress that a material will withstand without permanent deformation






35. Anything for which a person is legally bound or responsible






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






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






38. A device that responds to a physical stimulus






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






40. The use of quality control techniques associated with a process.






41. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






42. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






43. The state when objects are not yet in motion






44. Frequency distribution graph






45. The square root of the variance.






46. Used to start and stop flow in a circuit






47. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






49. 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.






50. 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
