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






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






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






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






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






6. Aircraft speeds between Mach 5 and 10.






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






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






9. 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.






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






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






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






13. Design machines that fly.






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






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






16. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






30. 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.






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






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






33. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






47. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.






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






49. To set or thrust in motion.






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