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 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. 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.






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






6. Design machines that fly.






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






8. Robotic aircraft - used extensively by the military.






9. 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.






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






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






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






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






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






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






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






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






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






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






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






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






22. The ratio of inertial forces to viscous forces.






23. 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.






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






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






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






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






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






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






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






31. Aircraft speeds under Mach 1.






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






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






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






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






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






37. Aircraft speeds between Mach 10 and 25.






38. 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.






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






40. 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.






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






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






43. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






49. Aircraft speeds between Mach 5 and 10.






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