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 relationship between the length and width of a wing.






2. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






18. Aircraft speeds under Mach 1.






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






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






21. Design machines that fly.






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






23. 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.






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






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






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






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






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






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






30. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






41. 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.






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






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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