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






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






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






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






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






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






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






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






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






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






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






12. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






14. To set or thrust in motion.






15. The ratio of inertial forces to viscous forces.






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






17. Aircraft speeds between Mach 5 and 10.






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






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






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






21. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






27. Robotic aircraft - used extensively by the military.






28. Design machines that fly.






29. Aircraft speeds between Mach 10 and 25.






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






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






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






33. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






49. 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.






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