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






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






3. 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.






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






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






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






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






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






9. The horizontal line that passes through the center of gravity of the aircraft - perpendicular to its flight path.






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






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






12. To set or thrust in motion.






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






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






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






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






17. A glider designed for sustained flight.






18. Robotic aircraft - used extensively by the military.






19. 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.






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






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






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






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






24. A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.






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






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






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






28. 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.






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






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






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






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






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






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






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






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






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






38. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






45. 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.






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






47. Design machines that fly.






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






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






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