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






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






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






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






5. 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.






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






25. To set or thrust in motion.






26. Aircraft speeds under Mach 1.






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






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






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






30. Design machines that fly.






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






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






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






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






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






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






37. 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.






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






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






40. Aircraft speeds between Mach 5 and 10.






41. 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.






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






43. 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.






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






50. The ratio of inertial forces to viscous forces.
