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 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.






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






3. 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.






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






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






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






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






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






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






10. 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.






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






12. 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.






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






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






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






16. 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.






17. Aircraft speeds between Mach 1 and 5.






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






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






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






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






22. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






30. A glider designed for sustained flight.






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






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






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






34. To set or thrust in motion.






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






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






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






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






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






48. Aircraft speeds between Mach 10 and 25.






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






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