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






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






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






5. Aircraft speeds under Mach 1.






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






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






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






9. Design machines that fly.






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






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






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






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






14. 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.






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






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






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






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






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






20. 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.






21. The ratio of inertial forces to viscous forces.






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






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






24. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






31. A glider designed for sustained flight.






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






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






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






35. Aircraft speeds between Mach 1 and 5.






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






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






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






39. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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