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






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






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






4. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






21. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






29. Aircraft speeds between Mach 10 and 25.






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






31. Aircraft speeds between Mach 1 and 5.






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






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






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






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






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






41. 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.






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






43. 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.






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






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






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






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






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






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






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