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 between Mach 10 and 25.






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






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






4. Design machines that fly.






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






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






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






8. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






17. 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.






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






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






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






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






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






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






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






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






26. 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.






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






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






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






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






31. Robotic aircraft - used extensively by the military.






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






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






34. Aircraft speeds under Mach 1.






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






36. To set or thrust in motion.






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






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






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






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






41. Aircraft speeds between Mach 1 and 5.






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






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






44. A glider designed for sustained flight.






45. 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.






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






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






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






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






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