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 force caused by the gravitational attraction of the Earth.






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






3. 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.






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






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






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






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






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






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






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






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






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






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






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






15. A glider designed for sustained flight.






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






17. The ratio of inertial forces to viscous forces.






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






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






20. 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.






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






22. Aircraft speeds between Mach 1 and 5.






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






24. Aircraft speeds under Mach 1.






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






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






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






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 rate at which temperature decreases with an increase in altitude.






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






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






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






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






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






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






36. Robotic aircraft - used extensively by the military.






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






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






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






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






41. 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.






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






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






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






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






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






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






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






49. Aircraft speeds between Mach 5 and 10.






50. To set or thrust in motion.
