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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. Aircraft speeds between Mach 10 and 25.






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






28. To set or thrust in motion.






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






30. Robotic aircraft - used extensively by the military.






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






32. 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.






33. Aircraft speeds between Mach 1 and 5.






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






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






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






37. 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.






38. Design machines that fly.






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






44. Aircraft speeds under Mach 1.






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






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






47. 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.






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






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






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