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






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






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






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






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






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






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






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






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






10. 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.






11. 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.






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






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






14. A glider designed for sustained flight.






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






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






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






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






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






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






21. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






27. The ratio of inertial forces to viscous forces.






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






29. 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.






30. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






40. 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.






41. Design machines that fly.






42. Aircraft speeds between Mach 1 and 5.






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






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






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






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






47. Robotic aircraft - used extensively by the military.






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






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






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