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






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






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






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






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






6. A glider designed for sustained flight.






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






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






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






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






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






12. 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.






13. 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.






14. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






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






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






17. Aircraft speeds between Mach 5 and 10.






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






19. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






28. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






38. Aircraft speeds under Mach 1.






39. 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.






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






41. The ratio of inertial forces to viscous forces.






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






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






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






45. 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.






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






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






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






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






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