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






2. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






16. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






18. The ratio of inertial forces to viscous forces.






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






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






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






22. Robotic aircraft - used extensively by the military.






23. To set or thrust in motion.






24. 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.






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






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






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






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






29. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






41. Aircraft speeds under Mach 1.






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






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






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






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






46. Aircraft speeds between Mach 10 and 25.






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






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






49. 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.






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