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






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






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






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






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






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






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






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






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






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






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 - easily- remembered slogan - verse - or tune.






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






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






17. The ratio of inertial forces to viscous forces.






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






19. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






32. 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.






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






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






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






36. 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.






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






38. Robotic aircraft - used extensively by the military.






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






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






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






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






43. 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.






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






45. 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.






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






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






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






49. Aircraft speeds between Mach 1 and 5.






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