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. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






12. A glider designed for sustained flight.






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






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






15. To set or thrust in motion.






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






17. 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.






18. A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.






19. Robotic aircraft - used extensively by the military.






20. 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.






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






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






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






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






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






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






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






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






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






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






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






32. The ratio of inertial forces to viscous forces.






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






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






35. 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.






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






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






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






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






50. 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.
