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






2. 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.






3. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






11. The ratio of inertial forces to viscous forces.






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






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






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






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






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






17. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






23. Robotic aircraft - used extensively by the military.






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






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






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






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






28. Aircraft speeds under Mach 1.






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






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






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






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






33. A glider designed for sustained flight.






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






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






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






37. 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.






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






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






40. Design machines that fly.






41. 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.






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






43. Aircraft speeds between Mach 5 and 10.






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






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






46. 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.






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






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






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






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