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






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






3. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






21. 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.






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






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






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






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






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






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






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






29. Aircraft speeds under Mach 1.






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






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






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






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






34. The ratio of inertial forces to viscous forces.






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






36. Aircraft speeds between Mach 5 and 10.






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






38. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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. 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.






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






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