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 outline shape of a wing when viewed from above.






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






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






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






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






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






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






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






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






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






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






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






13. Aircraft speeds between Mach 5 and 10.






14. 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.






15. Design machines that fly.






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






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






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






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






20. A glider designed for sustained flight.






21. 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.






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






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






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






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






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






27. Aircraft speeds under Mach 1.






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






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






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






31. To set or thrust in motion.






32. The ratio of inertial forces to viscous forces.






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






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






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






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






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






38. 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.






39. 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.






40. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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