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 1 and 5.






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






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






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






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






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






7. 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.






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






9. Robotic aircraft - used extensively by the military.






10. 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.






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






12. 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.






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






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






15. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






21. To set or thrust in motion.






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






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






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






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






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






28. 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.






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






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






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






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






33. Aircraft speeds under Mach 1.






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






35. Aircraft speeds between Mach 5 and 10.






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






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






38. 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.






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






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






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






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






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






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






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






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






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






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






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






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