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 common reference point for the three axes of the aircraft.






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






3. Aircraft speeds under Mach 1.






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






5. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






12. Aircraft speeds between Mach 10 and 25.






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






14. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






15. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






26. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






33. To set or thrust in motion.






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






35. A glider designed for sustained flight.






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






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






38. 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.






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






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






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






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






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






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






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






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






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






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






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






50. Aircraft speeds between Mach 1 and 5.
