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. 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.






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






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






4. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






14. 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.






15. Aircraft speeds between Mach 1 and 5.






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






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






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






19. Robotic aircraft - used extensively by the military.






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






21. 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.






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






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. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






41. The ratio of inertial forces to viscous forces.






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






43. A glider designed for sustained flight.






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






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






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






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






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






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






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