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






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






3. Aircraft speeds under Mach 1.






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






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






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






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






8. To set or thrust in motion.






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






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






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






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






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






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






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






16. 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.






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






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






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






20. Robotic aircraft - used extensively by the military.






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






22. The written text of a play - film - or broadcast.






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






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






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






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






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






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






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






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






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






32. Design machines that fly.






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






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






35. Aircraft speeds between Mach 5 and 10.






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






37. Aircraft speeds between Mach 10 and 25.






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






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






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






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






42. A glider designed for sustained flight.






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






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






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






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






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






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






50. 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.
