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






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






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






4. 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.






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






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






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






8. Aircraft speeds between Mach 5 and 10.






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






10. Robotic aircraft - used extensively by the military.






11. 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.






12. 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.






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






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






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






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






32. Aircraft speeds between Mach 10 and 25.






33. Design machines that fly.






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






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






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






37. To set or thrust in motion.






38. Aircraft speeds under Mach 1.






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






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






41. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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