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 resource that cannot be replaced once used






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






3. 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.






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






5. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






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






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






8. 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.






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






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






11. The volume of fluid that moves through a system in a given period of time.






12. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






13. A body subjected to pull.






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






15. The absolute value of a number






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

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






18. The result of an experiment






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






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






21. An energy source that will never run out






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






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






24. 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.






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






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






27. 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






28. The connection points of members of a truss






29. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






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






31. 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






32. A group of machined or handmade parts that fit together to form a self- contained unit.






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






34. A surface or shape exposed by making a straight cut through something at right angles to the axis.






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






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






37. 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






38. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






39. Used to transport fluid in a circuit






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






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

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






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






44. A device that responds to a physical stimulus






45. The rotating member of an electrical machine






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






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






48. The calculated likelihood that a given event will occur






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






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