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






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






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






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






5. Robotic aircraft - used extensively by the military.






6. To set or thrust in motion.






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






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






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






10. Consists of both the engine and propeller in a small airplane.






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






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






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






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






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






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






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






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






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






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






21. 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.






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






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






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






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






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






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






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






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






30. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






38. Aircraft speeds between Mach 10 and 25.






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






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






41. The ratio of inertial forces to viscous forces.






42. A glider designed for sustained flight.






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






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






45. Aircraft speeds between Mach 1 and 5.






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






47. Aircraft speeds between Mach 5 and 10.






48. 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.






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






50. 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.
