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






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






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






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






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






6. Aircraft speeds under Mach 1.






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






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






9. 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.






10. Aircraft speeds between Mach 5 and 10.






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






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






13. Aircraft speeds between Mach 1 and 5.






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






15. 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.






16. 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.






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






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






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






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






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






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






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






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






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






26. 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.






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






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






29. To set or thrust in motion.






30. 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.






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






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






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






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






35. Robotic aircraft - used extensively by the military.






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






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






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






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






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






41. A glider designed for sustained flight.






42. The ratio of inertial forces to viscous forces.






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






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






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






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






47. Design machines that fly.






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






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






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