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






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






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






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






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






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






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






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






9. Aircraft speeds between Mach 10 and 25.






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






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






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






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






14. Design machines that fly.






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






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






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






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






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






20. A glider designed for sustained flight.






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






22. The ratio of inertial forces to viscous forces.






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






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






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






26. 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.






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






42. 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.






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






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






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






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






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






48. 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.






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






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