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 - easily- remembered slogan - verse - or tune.






2. Aircraft speeds between Mach 5 and 10.






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






4. A glider designed for sustained flight.






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






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






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






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






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






10. 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.






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






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






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






14. 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.






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






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






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






18. Aircraft speeds under Mach 1.






19. Design machines that fly.






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






21. 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.






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






23. The ratio of inertial forces to viscous forces.






24. The art and science of designing - building - and operating manned or unmanned space objects






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






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






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






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






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






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






31. Aircraft speeds between Mach 10 and 25.






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






33. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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