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






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






3. 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.






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






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






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






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






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






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






10. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






28. Robotic aircraft - used extensively by the military.






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






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






31. 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.






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






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






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






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






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






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






38. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






44. 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.






45. Aircraft speeds between Mach 10 and 25.






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






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






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






49. The rate at which temperature decreases with an increase in altitude.






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