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






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






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






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






5. Aircraft speeds under Mach 1.






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






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






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






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






10. To set or thrust in motion.






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






12. Design machines that fly.






13. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






14. 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.






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






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






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






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






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






20. A glider designed for sustained flight.






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






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






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






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






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






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






27. 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.






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






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






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






31. 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.






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






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






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






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






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






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






38. 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.






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






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






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






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






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






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






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






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






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






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






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






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