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






2. 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.






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






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






5. A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.






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






7. An aircraft that is designed to fly without an engine.






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






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






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






11. Aircraft speeds under Mach 1.






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






13. 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.






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






15. A glider designed for sustained flight.






16. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






26. Design machines that fly.






27. The flat surfaces located behind the center of gravity tend to weathervane with the wind.






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






29. Aircraft speeds between Mach 5 and 10.






30. Houses the cabin - the cockpit and is a common attachment point for the other major components.






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






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






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






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






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






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






37. Robotic aircraft - used extensively by the military.






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






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






40. A vehicle - missile - or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.






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






42. The relationship between the length and width of a wing.






43. Aircraft speeds between Mach 10 and 25.






44. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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






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






48. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






49. Aircraft speeds between Mach 1 and 5.






50. Aircraft stability is the characteristic of an airplane in flight that causes it to return to a condition of equilibrium - or steady flight - after it is disturbed.
