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






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






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






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






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






6. 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.






7. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






15. Design machines that fly.






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






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






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






19. Robotic aircraft - used extensively by the military.






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






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






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






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






24. Aircraft speeds under Mach 1.






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






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






27. Aircraft speeds between Mach 1 and 5.






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






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






30. To set or thrust in motion.






31. 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.






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






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






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






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






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






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






38. 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.






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






44. A glider designed for sustained flight.






45. 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.






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






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






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






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






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