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






2. 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.






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






4. 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.






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






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






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






8. 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.






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






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






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






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






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






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






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






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






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






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






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






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






21. To set or thrust in motion.






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






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






24. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






44. Aircraft speeds under Mach 1.






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






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






47. The rate at which temperature decreases with an increase in altitude.






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






49. Aircraft speeds between Mach 1 and 5.






50. Robotic aircraft - used extensively by the military.
