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






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






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






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






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






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






8. Robotic aircraft - used extensively by the military.






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






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






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






12. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






22. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






29. 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.






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






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






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






33. The ratio of inertial forces to viscous forces.






34. 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.






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






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






37. Aircraft speeds between Mach 1 and 5.






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






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






40. 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.






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






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






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






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






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






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






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






48. A glider designed for sustained flight.






49. 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.






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