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. Aircraft speeds under Mach 1.






2. To set or thrust in motion.






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






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






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






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






7. The ratio of inertial forces to viscous forces.






8. Aircraft speeds between Mach 5 and 10.






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






10. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






28. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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. Aircraft speeds between Mach 10 and 25.






37. 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.






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






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






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






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






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






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






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






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






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






47. Aircraft speeds between Mach 1 and 5.






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






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






50. 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.
