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






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






3. Aircraft speeds between Mach 1 and 5.






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






5. A glider designed for sustained flight.






6. 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.






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






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






9. 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.






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






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






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






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






14. 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.






15. 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.






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






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






18. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






27. Robotic aircraft - used extensively by the military.






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






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






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






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






32. Aircraft speeds between Mach 10 and 25.






33. Aircraft speeds under Mach 1.






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






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






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






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






38. The ratio of inertial forces to viscous forces.






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






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






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






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






43. 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.






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






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






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






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






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






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






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