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 straight line through the center of gravity of the aircraft and at 90






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






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






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






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






6. To set or thrust in motion.






7. The ratio of inertial forces to viscous forces.






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






9. Aircraft speeds under Mach 1.






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






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






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






13. 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.






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






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






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






19. A glider designed for sustained flight.






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






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






22. Aircraft speeds between Mach 5 and 10.






23. Robotic aircraft - used extensively by the military.






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






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






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






27. Aircraft speeds between Mach 10 and 25.






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






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






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






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






32. Aircraft speeds between Mach 1 and 5.






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






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






35. Design machines that fly.






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






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






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






39. 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.






40. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






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






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






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






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






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






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






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






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






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






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