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






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






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






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






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






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






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






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






16. Aircraft speeds between Mach 1 and 5.






17. To set or thrust in motion.






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






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






20. Design machines that fly.






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






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






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






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






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






26. 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.






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






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






29. 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.






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






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






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






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






34. 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.






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






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






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






38. A glider designed for sustained flight.






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






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






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






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






43. Aircraft speeds under Mach 1.






44. 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.






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






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






47. Aircraft speeds between Mach 10 and 25.






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






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






50. 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.
