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






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






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






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






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






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






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






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






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






10. 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.






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






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






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






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






15. 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.






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






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






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






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






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






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






22. Design machines that fly.






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






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






25. Robotic aircraft - used extensively by the military.






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






27. Aircraft speeds under Mach 1.






28. 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.






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






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






31. Aircraft speeds between Mach 10 and 25.






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






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






34. 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.






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






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






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






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






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






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






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






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






43. The ratio of inertial forces to viscous forces.






44. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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