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






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






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






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






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






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






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






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






9. Design machines that fly.






10. To set or thrust in motion.






11. 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.






12. Aircraft speeds between Mach 10 and 25.






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






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






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






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






17. 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.






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






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






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






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






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






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






24. A glider designed for sustained flight.






25. Aircraft speeds under Mach 1.






26. Generates the lifting force that helps the airplane fly when air flows around it.






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






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






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






30. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






48. 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.






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






50. Robotic aircraft - used extensively by the military.
