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






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






3. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






20. 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.






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






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






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






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






25. Aircraft speeds under Mach 1.






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






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






28. Robotic aircraft - used extensively by the military.






29. Aircraft speeds between Mach 10 and 25.






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






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






32. 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.






33. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






48. To set or thrust in motion.






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






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