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






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






4. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






18. Aircraft speeds between Mach 1 and 5.






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






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






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






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






23. Aircraft speeds between Mach 10 and 25.






24. 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.






25. The space in the fuselage of a small airplane containing seats for the pilot - copilot - and sometimes passengers.






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






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






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






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






30. 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.






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






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






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






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






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






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






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






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






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






40. The ratio of inertial forces to viscous forces.






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






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






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






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






45. A glider designed for sustained flight.






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






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






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






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