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 relationship between the length and width of a wing.






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






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






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






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






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






7. The flat surfaces located behind the center of gravity tend to weathervane with the wind.






8. The ratio of inertial forces to viscous forces.






9. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






17. Aircraft speeds between Mach 10 and 25.






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






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






20. 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.






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






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






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






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






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






26. A glider designed for sustained flight.






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






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






29. 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.






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






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






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






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






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






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






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






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






38. 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.






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






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






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






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






43. 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.






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






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






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






47. Design machines that fly.






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






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






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