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






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






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






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






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






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






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






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






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






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






11. 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.






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






13. Aircraft speeds under Mach 1.






14. 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.






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






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






17. 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.






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






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






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






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






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






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






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






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






26. The ratio of inertial forces to viscous forces.






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






28. Aircraft speeds between Mach 5 and 10.






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






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






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






37. Robotic aircraft - used extensively by the military.






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






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






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






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






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






43. 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.






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






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






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






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






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






49. Aircraft speeds between Mach 1 and 5.






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