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






2. Robotic aircraft - used extensively by the military.






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






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






11. Aircraft speeds under Mach 1.






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






13. 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.






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






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






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






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






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






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






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






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






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






23. To set or thrust in motion.






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






25. 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.






26. A glider designed for sustained flight.






27. Design machines that fly.






28. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






35. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






42. Aircraft speeds between Mach 1 and 5.






43. 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.






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






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






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






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






48. 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.






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






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