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






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






3. To set or thrust in motion.






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






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






6. 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.






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






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






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






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






11. A glider designed for sustained flight.






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






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






14. Aircraft speeds under Mach 1.






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






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






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






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






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






20. Design machines that fly.






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






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






23. Aircraft speeds between Mach 5 and 10.






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






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






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






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






28. 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.






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






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






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






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






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






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






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






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






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






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






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






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






41. Aircraft speeds between Mach 1 and 5.






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






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






44. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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