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






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






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






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






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






6. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. 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.






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






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






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






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






29. 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.






30. Aircraft speeds under Mach 1.






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






32. 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.






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






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






35. 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.






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






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






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






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






40. To set or thrust in motion.






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






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






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






48. The ratio of inertial forces to viscous forces.






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






50. Aircraft speeds between Mach 5 and 10.
