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 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.






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






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






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






6. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






13. 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.






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






15. Robotic aircraft - used extensively by the military.






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






17. 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.






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






19. 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.






20. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






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






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






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






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






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






26. Aircraft speeds under Mach 1.






27. To set or thrust in motion.






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






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






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






31. Aircraft speeds between Mach 5 and 10.






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






33. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






43. Design machines that fly.






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






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






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






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






48. A powered heavier- than - air aircraft with fixed wings from which the aircraft derives most of its lift.






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






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