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






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






3. Aircraft speeds between Mach 5 and 10.






4. To set or thrust in motion.






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






6. 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.






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






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






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






10. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






21. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






44. Aircraft speeds between Mach 1 and 5.






45. Aircraft speeds between Mach 10 and 25.






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






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






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






49. The ratio of inertial forces to viscous forces.






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