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






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






3. 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.






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






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






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






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






8. To set or thrust in motion.






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






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






11. 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.






12. The ratio of inertial forces to viscous forces.






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






14. 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.






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






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






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






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






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






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






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






22. Aircraft speeds under Mach 1.






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






24. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






48. Aircraft speeds between Mach 5 and 10.






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






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