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. 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.






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






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






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






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






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






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






8. Aircraft speeds under Mach 1.






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






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






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






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






13. 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.






14. Aircraft speeds between Mach 5 and 10.






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






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






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






18. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Aircraft speeds between Mach 10 and 25.






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






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






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






38. The ratio of inertial forces to viscous forces.






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






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






41. To set or thrust in motion.






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






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






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






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






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






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






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






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






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