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






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






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






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






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






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






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






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






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






10. Aircraft speeds between Mach 1 and 5.






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






12. To set or thrust in motion.






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






14. 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.






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






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






17. Design machines that fly.






18. 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.






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






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






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






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






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






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






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






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






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






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






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






30. 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.






31. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






40. Aircraft speeds between Mach 10 and 25.






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






42. Aircraft speeds between Mach 5 and 10.






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






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






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






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






47. The ratio of inertial forces to viscous forces.






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






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






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