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 written text of a play - film - or broadcast.






2. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






8. Design machines that fly.






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






10. Aircraft speeds between Mach 5 and 10.






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






12. The ratio of inertial forces to viscous forces.






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






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






15. To set or thrust in motion.






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






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






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






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






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






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






22. 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.






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






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






25. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






34. Aircraft speeds under Mach 1.






35. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






49. 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.






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