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






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






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






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






15. 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.






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






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






18. 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.






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






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






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






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






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






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






25. 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.






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






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 1 and 5.






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






37. Aircraft speeds between Mach 5 and 10.






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






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






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






41. Aircraft speeds under Mach 1.






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






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






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






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






46. To set or thrust in motion.






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






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






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






50. 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.
