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. 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.






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






3. Consists of both the engine and propeller in a small airplane.






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






5. A glider designed for sustained flight.






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






7. To set or thrust in motion.






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






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






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






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






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






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






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






15. 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.






16. The ratio of inertial forces to viscous forces.






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






18. Robotic aircraft - used extensively by the military.






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






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






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






22. 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.






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






24. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






35. Design machines that fly.






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






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






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






39. 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.






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






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






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






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






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






45. Aircraft speeds between Mach 1 and 5.






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






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






48. 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.






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






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