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






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






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






4. 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.






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






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






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






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






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






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






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






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






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






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






15. Aircraft speeds under Mach 1.






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






17. 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.






18. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. To set or thrust in motion.






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






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






37. 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.






38. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






46. 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.






47. Aircraft speeds between Mach 5 and 10.






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






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






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