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 distance from wing tip to wing tip of a wing planform.






2. The art and science of designing - building - and operating manned or unmanned space objects






3. The study or practice of travel through the air.






4. Aircraft speeds under Mach 1.






5. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






6. The horizontal line that passes through the center of gravity of the aircraft - perpendicular to its flight path.






7. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.






8. The angle formed by the wing chord line and the relative wind.






9. Forces and moments on the body caused by a disturbance tend initially to return the body toward its equilibrium position.






10. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.






11. Design machines that fly.






12. Mach. A decimal number representing the true airspeed relationship to the local speed of sound.






13. Caused by the separation of airflow from the wing's upper surface resulting in a rapid decrease in lift.






14. Hinged main surface part that help control banking for a turn






15. An advertising film which promotes a product in an informative and supposedly objective style.






16. The rate at which temperature decreases with an increase in altitude.






17. Out of its own accord - an aircraft eventually returns to and remains at its equilibrium position over a period of time.






18. A sequence of drawings representing the shots planned for a film or television production.






19. A short - easily- remembered slogan - verse - or tune.






20. An aircraft with floats or skis instead of wheels - designed to land on and take off from water.






21. Forward- acting force which opposes drag and propels the aircraft through the air.






22. A rear vertical stabilizer that controls side- to- side or yawing motion of the aircraft nose.






23. A short - memorable phrase used in advertising or associated with a political party or group.






24. Characteristic of the aircraft that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuver.






25. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






26. A straight line through the center of gravity of the aircraft and at 90






27. Acts in the opposite direction of flight - opposes the forward- acting force of thrust - and limits the forward speed of the aircraft.






28. The common reference point for the three axes of the aircraft.






29. The written text of a play - film - or broadcast.






30. Rolling motion about the longitudinal axis caused by ailerons deflecting in opposite directions and controlled by twisting the yoke.






31. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






32. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






33. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.






34. The tail assembly of an aircraft - including the horizontal and vertical stabilizers - elevators and rudder.






35. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.






36. The study of forces and the resulting motion of objects through the air.






37. Generates the lifting force that helps the airplane fly when air flows around it.






38. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






39. A glider designed for sustained flight.






40. The mounting of wings so that the wingtips and higher than the wingroot.






41. A reduction in the chord of a wing as measured from the root to the tip of the wing.






42. Branch of technology and industry concerned with aviation and space flight.






43. A force caused by the gravitational attraction of the Earth.






44. The outline shape of a wing when viewed from above.






45. The space in the fuselage of a small airplane containing seats for the pilot - copilot - and sometimes passengers.






46. The force that created by the effect of airflow as it passes over and under the wing.






47. A powered heavier- than - air aircraft with fixed wings from which the aircraft derives most of its lift.






48. The movement about the vertical axis produced by the rudder and controlled by pedals.






49. The last point on an airfoil that interacts with the airflow around the wing.






50. The part of the airfoil that meets the airflow first.
