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






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






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






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






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






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






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






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






9. 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.






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






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






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






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






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






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






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






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






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






19. Aircraft speeds between Mach 1 and 5.






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






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






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






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






24. 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.






25. Aircraft speeds between Mach 10 and 25.






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






27. Design machines that fly.






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






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






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






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






32. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






43. The ratio of inertial forces to viscous forces.






44. Aircraft speeds between Mach 5 and 10.






45. A glider designed for sustained flight.






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






47. 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.






48. To set or thrust in motion.






49. 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.






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