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. Robotic aircraft - used extensively by the military.






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






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






4. 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.






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






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






7. Aircraft speeds between Mach 1 and 5.






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






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






10. 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.






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






12. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






30. Aircraft speeds under Mach 1.






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






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






33. 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.






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






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






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






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






38. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






48. Aircraft speeds between Mach 10 and 25.






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






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