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






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






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






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






5. Design machines that fly.






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






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






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






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






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






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






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






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






14. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






25. Aircraft speeds under Mach 1.






26. 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.






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






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






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






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






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






32. 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.






33. Aircraft speeds between Mach 5 and 10.






34. 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.






35. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






42. 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.






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






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






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






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






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






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






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






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