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. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






14. Aircraft speeds between Mach 10 and 25.






15. 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.






16. 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.






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






18. 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.






19. To set or thrust in motion.






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






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






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






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






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






25. Design machines that fly.






26. Aircraft speeds between Mach 5 and 10.






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






28. Aircraft speeds between Mach 1 and 5.






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






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






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






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






33. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






41. 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.






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






43. 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.






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






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






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






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






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






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






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