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 relationship between the length and width of a wing.






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






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






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






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






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






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






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






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






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






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






12. 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.






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






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






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






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






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






18. Design machines that fly.






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






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






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






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






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






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






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






26. 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.






27. Aircraft speeds between Mach 1 and 5.






28. Robotic aircraft - used extensively by the military.






29. Aircraft speeds under Mach 1.






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






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






32. To set or thrust in motion.






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






34. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






40. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






48. 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.






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






50. The ratio of inertial forces to viscous forces.
