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






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






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






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






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






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






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






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






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






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






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






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






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






14. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






21. Aircraft speeds under Mach 1.






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






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






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






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






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






27. Aircraft speeds between Mach 1 and 5.






28. Robotic aircraft - used extensively by the military.






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






30. Design machines that fly.






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






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






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






34. 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.






35. 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.






36. Aircraft speeds between Mach 10 and 25.






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






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






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






40. 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.






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






42. To set or thrust in motion.






43. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






49. 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.






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