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 part of the airfoil that meets the airflow first.






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






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






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






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






6. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






15. Aircraft speeds under Mach 1.






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






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






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






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






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






21. Aircraft speeds between Mach 10 and 25.






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






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






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






25. Design machines that fly.






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






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






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






29. The ratio of inertial forces to viscous forces.






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






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






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






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






34. 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.






35. 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.






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






37. 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.






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






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






40. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






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






42. To set or thrust in motion.






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






44. 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.






45. Robotic aircraft - used extensively by the military.






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






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






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






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






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