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






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






3. 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.






4. Aircraft speeds between Mach 1 and 5.






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






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






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






8. Aircraft speeds between Mach 5 and 10.






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






10. A glider designed for sustained flight.






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






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






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






14. Design machines that fly.






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






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






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






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






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






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






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






22. 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.






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






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






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






26. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






34. 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.






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






36. 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.






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






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






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






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






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






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






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






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






45. Robotic aircraft - used extensively by the military.






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






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






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






49. Aircraft speeds between Mach 10 and 25.






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