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






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






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






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






5. 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.






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






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






8. Aircraft speeds under Mach 1.






9. 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.






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






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






12. Aircraft speeds between Mach 1 and 5.






13. Robotic aircraft - used extensively by the military.






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






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






16. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






41. To set or thrust in motion.






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






43. 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.






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






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






46. Aircraft speeds between Mach 5 and 10.






47. Design machines that fly.






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






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






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