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






2. 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.






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






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






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






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






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






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






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






10. 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.






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






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






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






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






16. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






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






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






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






20. Design machines that fly.






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






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






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






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






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






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






27. To set or thrust in motion.






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






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






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






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






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






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






34. 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.






35. Aircraft speeds under Mach 1.






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






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






38. Aircraft speeds between Mach 5 and 10.






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






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






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






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






43. 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.






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






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






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






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






48. The ratio of inertial forces to viscous forces.






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






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