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






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






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






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






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






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






8. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 10 and 25.






25. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






36. The ratio of inertial forces to viscous forces.






37. Aircraft speeds between Mach 1 and 5.






38. 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.






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






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






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






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






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






44. 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.






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






46. Robotic aircraft - used extensively by the military.






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






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






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






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