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 force caused by the gravitational attraction of the Earth.






2. 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.






3. 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.






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






5. A glider designed for sustained flight.






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






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






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






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






10. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. Robotic aircraft - used extensively by the military.






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






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






30. The ratio of inertial forces to viscous forces.






31. 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.






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






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






34. 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.






35. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






49. To set or thrust in motion.






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