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






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






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






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






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






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






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






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






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






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






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






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






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






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






15. 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.






16. Aircraft speeds under Mach 1.






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






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






19. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






28. 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.






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






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






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






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






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






34. A glider designed for sustained flight.






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






36. Aircraft speeds between Mach 1 and 5.






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






38. Design machines that fly.






39. The ratio of inertial forces to viscous forces.






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






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






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






43. Robotic aircraft - used extensively by the military.






44. Aircraft speeds between Mach 5 and 10.






45. To set or thrust in motion.






46. 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.






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






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






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






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