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 glider designed for sustained flight.






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






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






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






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






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






7. The ratio of inertial forces to viscous forces.






8. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






31. Aircraft speeds between Mach 5 and 10.






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






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






34. 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.






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






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






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






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






39. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






49. 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.






50. Design machines that fly.
