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






2. Aircraft speeds between Mach 1 and 5.






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. Robotic aircraft - used extensively by the military.






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






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






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






9. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.






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






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






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






13. 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.






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






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






16. 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.






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






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






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






20. 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.






21. Consists of both the engine and propeller in a small airplane.






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






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






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






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






26. Aircraft speeds under Mach 1.






27. A short - easily- remembered slogan - verse - or tune.






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






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






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






31. Aircraft speeds between Mach 10 and 25.






32. A glider designed for sustained flight.






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






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






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






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






43. To set or thrust in motion.






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






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






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






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






48. 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.






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






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.
