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






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






3. Aircraft speeds under Mach 1.






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






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






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






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






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






9. Aircraft speeds between Mach 10 and 25.






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






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






12. 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.






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






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






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






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






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






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






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






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






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






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






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






24. 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.






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






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






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






28. 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.






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






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






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






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






33. To set or thrust in motion.






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






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






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






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






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






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






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






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






42. Aircraft speeds between Mach 1 and 5.






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






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






45. 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.






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






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






48. Robotic aircraft - used extensively by the military.






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






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