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 force caused by the gravitational attraction of the Earth.






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






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






4. 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.






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






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






7. To set or thrust in motion.






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






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






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






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






12. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






19. Design machines that fly.






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






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






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






23. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






39. Aircraft speeds under Mach 1.






40. Robotic aircraft - used extensively by the military.






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






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






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






44. 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.






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






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






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






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






49. 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.






50. The ratio of inertial forces to viscous forces.
