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






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






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






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






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






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






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






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






10. The ratio of inertial forces to viscous forces.






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






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






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






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






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






16. Design machines that fly.






17. A glider designed for sustained flight.






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






19. Aircraft speeds between Mach 10 and 25.






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






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






22. 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.






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






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






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






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






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






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






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






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






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






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






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






34. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






45. Robotic aircraft - used extensively by the military.






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






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






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






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






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