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






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






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






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






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






7. 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.






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






9. Robotic aircraft - used extensively by the military.






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






11. A glider designed for sustained flight.






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






13. To set or thrust in motion.






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






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






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






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






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






19. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. Aircraft speeds between Mach 1 and 5.






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






45. Design machines that fly.






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






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






48. Aircraft speeds between Mach 10 and 25.






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






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