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 glider designed for sustained flight.






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






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






4. The ratio of inertial forces to viscous forces.






5. 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.






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






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






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






14. 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.






15. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






23. Aircraft speeds under Mach 1.






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






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






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






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






28. Design machines that fly.






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






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






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






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






33. The tail assembly of an aircraft - including the horizontal and vertical stabilizers - elevators and rudder.






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






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






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






37. Aircraft speeds between Mach 10 and 25.






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






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






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






42. 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.






43. Aircraft speeds between Mach 5 and 10.






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






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






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






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






48. To set or thrust in motion.






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






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