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






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






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






4. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






10. 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.






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






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






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






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






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






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






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






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






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






20. 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.






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






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






23. The ratio of inertial forces to viscous forces.






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






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






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






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






28. 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.






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






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






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






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






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






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






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






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






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






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






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






40. 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.






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






42. Robotic aircraft - used extensively by the military.






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






44. 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.






45. A glider designed for sustained flight.






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






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






48. Aircraft speeds between Mach 5 and 10.






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






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