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. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.






2. The ratio of inertial forces to viscous forces.






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






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






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






6. 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.






7. A glider designed for sustained flight.






8. 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.






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






10. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






11. 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.






12. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






25. Robotic aircraft - used extensively by the military.






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






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






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






29. Aircraft speeds between Mach 1 and 5.






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






31. 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.






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






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






34. 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.






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






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






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






38. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






49. Aircraft speeds between Mach 10 and 25.






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