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 common reference point for the three axes of the aircraft.






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






3. The ratio of inertial forces to viscous forces.






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






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






6. Aircraft speeds between Mach 1 and 5.






7. To set or thrust in motion.






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






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






10. Design machines that fly.






11. A sequence of drawings representing the shots planned for a film or television production.






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






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






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






15. 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.






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






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






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






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






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






21. 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.






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






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






24. Aircraft speeds between Mach 10 and 25.






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






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






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






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






29. 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.






30. Aircraft speeds under Mach 1.






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






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






33. Robotic aircraft - used extensively by the military.






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 study or practice of travel through the air.






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






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






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






40. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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