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






2. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






9. 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.






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






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






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






13. Aircraft speeds between Mach 1 and 5.






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






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






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






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






18. 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.






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






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






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






22. 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.






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






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






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






26. To set or thrust in motion.






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






28. A glider designed for sustained flight.






29. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






39. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






47. Aircraft speeds between Mach 5 and 10.






48. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






50. Design machines that fly.
