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. Aircraft speeds between Mach 1 and 5.






2. To set or thrust in motion.






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






4. Aircraft speeds between Mach 10 and 25.






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






6. Aircraft speeds between Mach 5 and 10.






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






8. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. The ratio of inertial forces to viscous forces.






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






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






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






28. A glider designed for sustained flight.






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






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






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






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






33. 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.






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






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






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






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






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






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






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






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






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






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






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






45. 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.






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






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






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






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






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