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






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






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






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






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






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






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






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






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






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






11. 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.






12. 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.






13. 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.






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






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






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






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






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






19. Aircraft speeds between Mach 1 and 5.






20. To set or thrust in motion.






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






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






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






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






25. Aircraft speeds between Mach 10 and 25.






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






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






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






29. Aircraft speeds between Mach 5 and 10.






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






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






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






33. Aircraft speeds under Mach 1.






34. The ratio of inertial forces to viscous forces.






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






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






37. Robotic aircraft - used extensively by the military.






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






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






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






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






42. A glider designed for sustained flight.






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






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






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






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






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






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






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






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