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






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






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






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






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






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






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






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






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






10. Design machines that fly.






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






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






13. Aircraft speeds between Mach 5 and 10.






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






15. 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.






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






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






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






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






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






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






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






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






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






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






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






27. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.






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






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






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






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






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






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






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






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






36. The ratio of inertial forces to viscous forces.






37. A glider designed for sustained flight.






38. Aircraft speeds between Mach 1 and 5.






39. To set or thrust in motion.






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






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






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






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






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






45. Aircraft speeds between Mach 10 and 25.






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






47. 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.






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






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






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