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






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






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






4. Aircraft speeds under Mach 1.






5. A glider designed for sustained flight.






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






7. Robotic aircraft - used extensively by the military.






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






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






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






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






12. 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.






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






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






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






16. Aircraft speeds between Mach 1 and 5.






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






18. 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.






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






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






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






22. To set or thrust in motion.






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






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






25. Design machines that fly.






26. Aircraft speeds between Mach 10 and 25.






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






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






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






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






31. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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 rate at which temperature decreases with an increase in altitude.






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






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






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






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






48. 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.






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






50. 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.
