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






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






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






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






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






6. A glider designed for sustained flight.






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






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






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






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






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






12. 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.






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






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






15. 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.






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






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






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






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






20. Aircraft speeds under Mach 1.






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






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






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






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






25. Robotic aircraft - used extensively by the military.






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






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






28. To set or thrust in motion.






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






30. Design machines that fly.






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






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






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






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






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






36. 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.






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






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






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






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






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






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






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






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






45. The ratio of inertial forces to viscous forces.






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






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






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






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






50. Aircraft speeds between Mach 1 and 5.
