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 common reference point for the three axes of the aircraft.






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






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






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






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






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






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






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






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






11. 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.






12. A glider designed for sustained flight.






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






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






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






16. 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.






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






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






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






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






21. Aircraft speeds between Mach 10 and 25.






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






23. 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.






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






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






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






27. Aircraft speeds between Mach 1 and 5.






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






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






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






31. Robotic aircraft - used extensively by the military.






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






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






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






35. Design machines that fly.






36. The ratio of inertial forces to viscous forces.






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






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






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






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






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






42. To set or thrust in motion.






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






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






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






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






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






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






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






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