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






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






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






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






5. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






22. Aircraft speeds under Mach 1.






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






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






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






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






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






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






29. The ratio of inertial forces to viscous forces.






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






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






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






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






34. 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.






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






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






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






38. 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.






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






40. To set or thrust in motion.






41. 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.






42. A glider designed for sustained flight.






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






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






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






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






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






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






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






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