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






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






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






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






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






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






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






8. Aircraft speeds under Mach 1.






9. 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.






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






11. The ratio of inertial forces to viscous forces.






12. 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.






13. Design machines that fly.






14. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






28. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






41. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






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






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






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






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






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






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






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






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






50. 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.
