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. Aircraft speeds between Mach 1 and 5.






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






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






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






6. 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.






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






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






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






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






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






12. To set or thrust in motion.






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






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






15. A glider designed for sustained flight.






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






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






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






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






20. 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.






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






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






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






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






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






26. Aircraft speeds between Mach 5 and 10.






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






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






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






30. 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.






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






32. Robotic aircraft - used extensively by the military.






33. 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.






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






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






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






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






38. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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