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






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






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






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






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






6. 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.






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






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






9. Design machines that fly.






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






11. Aircraft speeds between Mach 1 and 5.






12. Aircraft speeds between Mach 5 and 10.






13. 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.






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






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






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






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






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






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






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






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






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






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






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






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






26. 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.






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






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






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






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






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






32. Robotic aircraft - used extensively by the military.






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






34. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






45. To set or thrust in motion.






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






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






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






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






50. 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.
