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






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






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






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






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






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






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






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






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






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






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






12. Aircraft speeds under Mach 1.






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






14. 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.






15. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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. The ratio of inertial forces to viscous forces.






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






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






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






31. Aircraft speeds between Mach 10 and 25.






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






33. 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.






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






35. 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.






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






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






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






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






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






41. 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.






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






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






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






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






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






47. To set or thrust in motion.






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






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






50. 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.
