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






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






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






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






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






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






7. 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.






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






17. Aircraft speeds under Mach 1.






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






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






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






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






22. The ratio of inertial forces to viscous forces.






23. Aircraft speeds between Mach 10 and 25.






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






25. 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.






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






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






28. A glider designed for sustained flight.






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






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






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






32. Aircraft speeds between Mach 5 and 10.






33. Robotic aircraft - used extensively by the military.






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






35. To set or thrust in motion.






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






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






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






39. 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.






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






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






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






43. 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.






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






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






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






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






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






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






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