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






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






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






4. 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.






5. Robotic aircraft - used extensively by the military.






6. Aircraft speeds under Mach 1.






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






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






17. 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.






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






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






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






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






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






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






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






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






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






27. 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.






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






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






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






31. Aircraft speeds between Mach 5 and 10.






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






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






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






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






36. Design machines that fly.






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






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






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






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






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






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






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






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






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






46. A glider designed for sustained flight.






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






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






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






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