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






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






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






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






5. A glider designed for sustained flight.






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






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






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






9. Aircraft speeds under Mach 1.






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






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






12. 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.






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






14. Aircraft speeds between Mach 1 and 5.






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






16. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






27. 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.






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






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






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






31. 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.






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






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






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






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






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






50. To set or thrust in motion.
