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. Design machines that fly.






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






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






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






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






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






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






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






9. Aircraft speeds between Mach 5 and 10.






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






11. 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.






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






13. A glider designed for sustained flight.






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






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






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






17. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. 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.






35. 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.






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






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






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






39. Aircraft speeds under Mach 1.






40. 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.






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






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






43. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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