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






2. The ratio of inertial forces to viscous forces.






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






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






5. Aircraft speeds under Mach 1.






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






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






8. 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.






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






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






12. Aircraft speeds between Mach 10 and 25.






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






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






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






16. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






25. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






38. 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.






39. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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