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






2. A glider designed for sustained flight.






3. 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.






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






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






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






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






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






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






10. 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.






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






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






13. 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.






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






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






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






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






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






19. The ratio of inertial forces to viscous forces.






20. Robotic aircraft - used extensively by the military.






21. Design machines that fly.






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






23. Aircraft speeds under Mach 1.






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






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






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






27. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 5 and 10.






46. Aircraft speeds between Mach 10 and 25.






47. Aircraft speeds between Mach 1 and 5.






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






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






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