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. Aircraft speeds between Mach 10 and 25.






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






3. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






15. 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.






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






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






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






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






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






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






22. A glider designed for sustained flight.






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






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






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






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






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






28. Aircraft speeds under Mach 1.






29. 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.






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






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






32. Design machines that fly.






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






34. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






41. 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.






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






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






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






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






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






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






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






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






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