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 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.






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






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






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






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






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






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






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






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






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






11. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






19. 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.






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






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






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






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






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






25. 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.






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






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






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






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






30. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






37. A glider designed for sustained flight.






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






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






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






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






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






43. Aircraft speeds between Mach 10 and 25.






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






45. Design machines that fly.






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






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






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






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






50. Aircraft speeds under Mach 1.
