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






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






3. Aircraft speeds between Mach 10 and 25.






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






5. Robotic aircraft - used extensively by the military.






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






7. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






16. 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.






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






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






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






20. 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.






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






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






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






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






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






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






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






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






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






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






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






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






33. To set or thrust in motion.






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






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






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






41. The ratio of inertial forces to viscous forces.






42. 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.






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






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






45. 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.






46. The rate at which temperature decreases with an increase in altitude.






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






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






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






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