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






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






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






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






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 1 and 5.






21. Aircraft speeds under Mach 1.






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






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






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






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






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






27. Robotic aircraft - used extensively by the military.






28. The distance from wing tip to wing tip of a wing planform.






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






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






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






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






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






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






35. 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.






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






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






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






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






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






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






42. Aircraft speeds between Mach 10 and 25.






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






44. 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.






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






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






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






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






50. The ratio of inertial forces to viscous forces.
