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






3. Aircraft speeds between Mach 5 and 10.






4. 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.






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






6. Robotic aircraft - used extensively by the military.






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






8. 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.






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






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






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






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






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






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






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






16. 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.






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






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






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






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






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






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






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






24. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. A glider designed for sustained flight.






47. 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.






48. Aircraft speeds between Mach 1 and 5.






49. Aircraft speeds between Mach 10 and 25.






50. The ratio of inertial forces to viscous forces.
