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. 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.






2. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






8. 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.






9. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






17. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






28. To set or thrust in motion.






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






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






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






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






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






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






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






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






37. 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.






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






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






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






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






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






43. Robotic aircraft - used extensively by the military.






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






45. 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.






46. Design machines that fly.






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






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






49. 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.






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