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






2. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






8. Design machines that fly.






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






10. Robotic aircraft - used extensively by the military.






11. 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.






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






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






14. To set or thrust in motion.






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






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






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






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






19. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






33. 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.






34. A glider designed for sustained flight.






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






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






37. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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