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






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






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






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






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






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






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






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






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






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






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






12. Robotic aircraft - used extensively by the military.






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






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






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






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






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






18. Design machines that fly.






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






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






21. Aircraft speeds between Mach 10 and 25.






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






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






24. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






37. 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.






38. 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.






39. 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.






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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