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. 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.






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






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






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






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






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






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






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






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






11. 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.






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






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






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






15. Robotic aircraft - used extensively by the military.






16. To set or thrust in motion.






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






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






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






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






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






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






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






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






25. 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.






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






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 10 and 25.






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






37. 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.






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






39. 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.






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






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






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






43. A glider designed for sustained flight.






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






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






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






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






48. Aircraft speeds between Mach 5 and 10.






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






50. The ratio of inertial forces to viscous forces.
