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






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






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






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






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






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






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






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






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






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






11. Aircraft speeds under Mach 1.






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






13. A glider designed for sustained flight.






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






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






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






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






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






19. 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.






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






21. Robotic aircraft - used extensively by the military.






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






23. 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.






24. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






34. The ratio of inertial forces to viscous forces.






35. Aircraft speeds between Mach 1 and 5.






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






37. Design machines that fly.






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






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






40. 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.






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






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






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






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






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






47. 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.






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






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






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