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






2. Robotic aircraft - used extensively by the military.






3. Aircraft speeds between Mach 1 and 5.






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






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






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






7. 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.






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






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






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






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






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






13. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






21. 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.






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






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






24. 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.






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






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






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






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






29. The ratio of inertial forces to viscous forces.






30. Aircraft speeds between Mach 5 and 10.






31. Design machines that fly.






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






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






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






35. A glider designed for sustained flight.






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






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






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






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






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






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






42. 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.






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






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






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






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






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






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






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






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