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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






19. 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.






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






21. 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.






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






23. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






34. Design machines that fly.






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






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






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






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






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






41. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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