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






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






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






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






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






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






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






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






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






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






11. The ratio of inertial forces to viscous forces.






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






13. Aircraft speeds between Mach 5 and 10.






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






15. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






25. To set or thrust in motion.






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






27. 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.






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






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






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






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






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






33. Robotic aircraft - used extensively by the military.






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






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






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






37. Design machines that fly.






38. 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.






39. A glider designed for sustained flight.






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






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






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






43. 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.






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






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






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






47. 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.






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






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






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