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






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






3. Aircraft speeds under Mach 1.






4. A glider designed for sustained flight.






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






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






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






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






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






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






12. To set or thrust in motion.






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






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






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






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






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






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






19. 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.






20. 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.






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






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






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






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






25. 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.






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






27. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. Aircraft speeds between Mach 10 and 25.






44. Robotic aircraft - used extensively by the military.






45. Aircraft speeds between Mach 5 and 10.






46. 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.






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






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






49. 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.






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