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






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






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






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






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






6. 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.






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






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






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






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






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






12. Aircraft speeds between Mach 10 and 25.






13. 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.






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






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






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






19. Design machines that fly.






20. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






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






22. Aircraft speeds between Mach 5 and 10.






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






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






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






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






27. Aircraft speeds under Mach 1.






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






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






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






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






32. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






45. The ratio of inertial forces to viscous forces.






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






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






48. The outline shape of a wing when viewed from above.






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






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