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






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






3. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






13. 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.






14. 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.






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






16. Design machines that fly.






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






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






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






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






21. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






33. 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.






34. 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.






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






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






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






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






39. To set or thrust in motion.






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






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






42. Robotic aircraft - used extensively by the military.






43. Aircraft speeds between Mach 1 and 5.






44. Aircraft speeds between Mach 10 and 25.






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






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






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






48. 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.






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






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