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






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






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






5. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






17. Aircraft speeds between Mach 10 and 25.






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






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






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






21. 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.






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






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






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






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






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






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






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






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






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






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






32. Robotic aircraft - used extensively by the military.






33. 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.






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






35. To set or thrust in motion.






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






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






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






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






40. 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.






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






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






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






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






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






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






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






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






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






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