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






2. The ratio of inertial forces to viscous forces.






3. 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.






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






5. Aircraft speeds between Mach 10 and 25.






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






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






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






9. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. Aircraft speeds under Mach 1.






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






28. 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.






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






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






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






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






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






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






35. To set or thrust in motion.






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






37. 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.






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






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






40. Aircraft speeds between Mach 5 and 10.






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






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






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






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






45. 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.






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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