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 written text of a play - film - or broadcast.






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






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






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






5. Aircraft speeds between Mach 10 and 25.






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






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






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






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






10. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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






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






14. 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.






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






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






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






18. Aircraft speeds between Mach 1 and 5.






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






20. Design machines that fly.






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






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






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






24. Robotic aircraft - used extensively by the military.






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






26. Aircraft speeds between Mach 5 and 10.






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






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






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






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






31. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






39. Aircraft speeds under Mach 1.






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






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






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






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






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






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






46. A glider designed for sustained flight.






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






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






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






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