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. 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.






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






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






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






5. Aircraft speeds between Mach 1 and 5.






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






7. 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.






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






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






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






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






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






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






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






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






16. Aircraft speeds under Mach 1.






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






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






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






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






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






22. Aircraft speeds between Mach 5 and 10.






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






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






25. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






32. 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.






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






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






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






36. 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.






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






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






39. The ratio of inertial forces to viscous forces.






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






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






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






43. To set or thrust in motion.






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






45. Robotic aircraft - used extensively by the military.






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






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






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






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






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