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 relationship between the length and width of a wing.






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






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






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






5. 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.






6. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






16. Robotic aircraft - used extensively by the military.






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






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






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






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






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






22. Aircraft speeds between Mach 1 and 5.






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






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






25. Design machines that fly.






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






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






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






29. Aircraft speeds between Mach 10 and 25.






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






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






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






33. 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.






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






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






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






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






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






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






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






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






42. 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.






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






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






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






46. 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.






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






48. 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.






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






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