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. To set or thrust in motion.






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






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






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






6. The ratio of inertial forces to viscous forces.






7. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






18. Robotic aircraft - used extensively by the military.






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






20. 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.






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






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






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






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






25. Aircraft speeds under Mach 1.






26. 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.






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






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






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






30. Design machines that fly.






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






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






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






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






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






36. 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.






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






38. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






44. 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.






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






46. The movement about the vertical axis produced by the rudder and controlled by pedals.






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






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






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






50. Aircraft speeds between Mach 10 and 25.
