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 speeds under Mach 1.






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






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






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






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






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






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






8. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






15. The part of the airfoil that meets the airflow first.






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






17. To set or thrust in motion.






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






19. Aircraft speeds between Mach 10 and 25.






20. 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.






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






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






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






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






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






26. 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.






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






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






29. 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.






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






31. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. The ratio of inertial forces to viscous forces.






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






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






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