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






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






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






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






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






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






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






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






9. Aircraft speeds between Mach 5 and 10.






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






11. The ratio of inertial forces to viscous forces.






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






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






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






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






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






17. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






39. 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.






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






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






42. Aircraft speeds between Mach 1 and 5.






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






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






45. A glider designed for sustained flight.






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






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






48. 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.






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






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