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






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






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






4. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






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






23. Aircraft speeds between Mach 1 and 5.






24. 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.






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






26. A glider designed for sustained flight.






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






28. 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.






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






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






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






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






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






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






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






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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 part of the airfoil that meets the airflow first.






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






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






45. Robotic aircraft - used extensively by the military.






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






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






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






49. 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.






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