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






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






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






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






5. 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.






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






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






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






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






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






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






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






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






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






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






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






17. To set or thrust in motion.






18. Aircraft speeds between Mach 10 and 25.






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






20. Aircraft speeds between Mach 1 and 5.






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






22. Robotic aircraft - used extensively by the military.






23. 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.






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






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






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






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






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






29. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






41. 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.






42. Aircraft speeds between Mach 5 and 10.






43. 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.






44. Aircraft speeds under Mach 1.






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






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






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






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






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






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