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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






17. Aircraft speeds under Mach 1.






18. Robotic aircraft - used extensively by the military.






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






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






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






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






23. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






33. Aircraft speeds between Mach 1 and 5.






34. 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.






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






36. Design machines that fly.






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






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






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






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






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






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






43. To set or thrust in motion.






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






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






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






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






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






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. Aircraft speeds between Mach 5 and 10.
