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 study or practice of travel through the air.






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






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






4. Aircraft speeds under Mach 1.






5. Aircraft speeds between Mach 5 and 10.






6. To set or thrust in motion.






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






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






9. Design machines that fly.






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






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






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






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






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






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






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






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






18. 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.






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






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






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






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






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






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. 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.






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






27. A glider designed for sustained flight.






28. Aircraft speeds between Mach 10 and 25.






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






30. 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.






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






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






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






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






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






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






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






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






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






40. 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.






41. Robotic aircraft - used extensively by the military.






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






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






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






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






46. 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.






47. Aircraft speeds between Mach 1 and 5.






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






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






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