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






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






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






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






5. Aircraft speeds between Mach 1 and 5.






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






7. 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.






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






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






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






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






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






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






15. Aircraft speeds between Mach 5 and 10.






16. The ratio of inertial forces to viscous forces.






17. 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.






18. A glider designed for sustained flight.






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






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






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






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






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






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






25. 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.






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






27. 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.






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






29. Aircraft speeds between Mach 10 and 25.






30. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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. Robotic aircraft - used extensively by the military.






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






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






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






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






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






47. Aircraft speeds under Mach 1.






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






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






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