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. 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.






2. To set or thrust in motion.






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






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






5. Aircraft speeds between Mach 5 and 10.






6. A glider designed for sustained flight.






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






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






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






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






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






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






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






14. Design machines that fly.






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






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






17. Aircraft speeds between Mach 10 and 25.






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






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






20. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






30. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






39. 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.






40. A sequence of drawings representing the shots planned for a film or television production.






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






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






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






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






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






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






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






48. 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.






49. 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.






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