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






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






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






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






5. Design machines that fly.






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






7. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






22. The ratio of inertial forces to viscous forces.






23. 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.






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






25. Robotic aircraft - used extensively by the military.






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






27. A glider designed for sustained flight.






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






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






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






31. To set or thrust in motion.






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






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






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






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






36. 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.






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






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






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






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






41. 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.






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






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






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






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






46. 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.






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






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






49. Aircraft speeds under Mach 1.






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