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 written text of a play - film - or broadcast.






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






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






4. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






11. To set or thrust in motion.






12. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.






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






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






15. A glider designed for sustained flight.






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






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






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






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






20. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






34. 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.






35. 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.






36. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






37. Aircraft speeds between Mach 1 and 5.






38. Robotic aircraft - used extensively by the military.






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






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






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






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






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






44. Aircraft speeds under Mach 1.






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






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






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






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






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






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