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






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






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






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






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






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






7. 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.






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






9. 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.






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






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






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






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






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






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






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






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






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






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






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






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






22. 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.






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






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






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






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






27. Aircraft speeds under Mach 1.






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






29. 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.






30. A glider designed for sustained flight.






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






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






33. Aircraft speeds between Mach 5 and 10.






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






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






36. A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.






37. To set or thrust in motion.






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






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






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






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






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






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






44. Aircraft speeds between Mach 10 and 25.






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






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






47. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.






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






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






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