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. Aircraft speeds under Mach 1.






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






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






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






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






6. Design machines that fly.






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






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






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






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






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






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






13. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






20. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






28. Aircraft speeds between Mach 10 and 25.






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






30. 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.






31. 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.






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






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






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






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






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






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






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






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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