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






2. Aircraft speeds under Mach 1.






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






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






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






6. 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.






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






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






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






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






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






12. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






31. Robotic aircraft - used extensively by the military.






32. 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.






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






34. A glider designed for sustained flight.






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






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






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






38. The ratio of inertial forces to viscous forces.






39. 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.






40. 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.






41. Aircraft speeds between Mach 10 and 25.






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






43. Aircraft speeds between Mach 5 and 10.






44. To set or thrust in motion.






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






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






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






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






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






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