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






3. A glider designed for sustained flight.






4. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






13. Aircraft speeds between Mach 5 and 10.






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






15. Design machines that fly.






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






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






18. Aircraft speeds between Mach 1 and 5.






19. 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.






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






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






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






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






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






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






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






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






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






29. 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.






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






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






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






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






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






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






36. Aircraft speeds under Mach 1.






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






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






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






41. 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.






42. To set or thrust in motion.






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






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






45. The ratio of inertial forces to viscous forces.






46. Robotic aircraft - used extensively by the military.






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






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






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






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