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






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






3. Design machines that fly.






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






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






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 5 and 10.






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






22. Aircraft speeds between Mach 1 and 5.






23. Aircraft speeds under Mach 1.






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






25. 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.






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






27. 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.






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






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






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






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






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






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






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






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






36. 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.






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






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






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






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






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






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






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






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






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






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






47. A glider designed for sustained flight.






48. The ratio of inertial forces to viscous forces.






49. To set or thrust in motion.






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