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






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






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






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






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






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






7. Robotic aircraft - used extensively by the military.






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






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






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






11. 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.






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






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






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






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






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






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






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






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






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






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






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






23. Aircraft speeds between Mach 10 and 25.






24. A glider designed for sustained flight.






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






26. 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.






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






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






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






30. 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.






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






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






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






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






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






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






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






38. 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.






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






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






46. 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.






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






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






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






50. Design machines that fly.
