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. Robotic aircraft - used extensively by the military.






2. 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.






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






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






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






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






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






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






9. The ratio of inertial forces to viscous forces.






10. Aircraft speeds between Mach 5 and 10.






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






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






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






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






15. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






24. A glider designed for sustained flight.






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






26. 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.






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






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






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






39. 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.






40. 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.






41. To set or thrust in motion.






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






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






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






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






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






47. Aircraft speeds between Mach 1 and 5.






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






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






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