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






2. The ratio of inertial forces to viscous forces.






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






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






5. 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.






6. Aircraft speeds between Mach 10 and 25.






7. 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.






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






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






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






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






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






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






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






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






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






17. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






23. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






34. A glider designed for sustained flight.






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






36. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






49. Robotic aircraft - used extensively by the military.






50. Design machines that fly.
