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 glider designed for sustained flight.






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






3. 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.






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






5. Aircraft speeds between Mach 10 and 25.






6. 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.






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






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






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






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






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






12. 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.






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






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






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






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






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






18. The ratio of inertial forces to viscous forces.






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






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






21. To set or thrust in motion.






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






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






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






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






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






27. Aircraft speeds under Mach 1.






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






29. Aircraft speeds between Mach 1 and 5.






30. Robotic aircraft - used extensively by the military.






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






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






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






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






35. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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