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






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






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






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






5. 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.






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






7. Design machines that fly.






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






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






10. Aircraft speeds between Mach 1 and 5.






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






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






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






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






15. 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.






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 5 and 10.






25. To set or thrust in motion.






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






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






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






29. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






38. The study or practice of travel through the air.






39. 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.






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






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






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






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






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






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






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






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






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






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






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