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






2. Aircraft speeds between Mach 5 and 10.






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






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






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






6. 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.






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






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






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






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






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






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






13. Aircraft speeds under Mach 1.






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






15. 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.






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






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






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






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






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






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






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






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






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






25. 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.






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






27. A glider designed for sustained flight.






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






29. 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.






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






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






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






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






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






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






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






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






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






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






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






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






42. Aircraft speeds between Mach 10 and 25.






43. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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