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






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






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






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






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






6. 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.






7. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






8. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






9. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






11. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






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






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






14. A sketch that shows an object's height - width - and depth in a single view.






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






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






17. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






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

19. Change in length of an object in some direction per unit






20. 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






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






22. The use of a liquid flowing under pressure to transmit power from one location to another






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






24. A law that states all natural processes proceed in a preferred direction






25. The condition of a string - wire - or rod that is stretched between two points






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






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






28. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






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






30. 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.






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






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






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






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






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






36. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






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






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






39. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






40. 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






41. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






42. An energy source that will never run out






43. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






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






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






46. 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






47. Used to transport fluid in a circuit






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






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






50. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.
