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






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






3. The ratio of inertial forces to viscous forces.






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






5. Aircraft speeds between Mach 5 and 10.






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






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






9. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






22. Design machines that fly.






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






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






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






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






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






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






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






30. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






31. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. A glider designed for sustained flight.






48. 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.






49. 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.






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