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






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






4. Design machines that fly.






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






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






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






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






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






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






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






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






13. Aircraft speeds between Mach 10 and 25.






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






15. To set or thrust in motion.






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






17. Aircraft speeds between Mach 5 and 10.






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






19. 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.






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






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






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






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






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






26. Robotic aircraft - used extensively by the military.






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






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






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






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






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






32. 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.






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






34. The ratio of inertial forces to viscous forces.






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






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






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






38. 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.






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






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






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






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






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






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






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






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






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






48. Branch of technology and industry concerned with aviation and space flight.






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






50. Aircraft speeds between Mach 1 and 5.
