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






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






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






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






5. 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.






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






7. The ratio of inertial forces to viscous forces.






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






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






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






11. Aircraft speeds between Mach 5 and 10.






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






13. 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.






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






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






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






17. To set or thrust in motion.






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






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






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






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






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






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






24. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






32. 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.






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






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






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






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






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






38. 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.






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






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






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






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






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






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






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






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






47. Design machines that fly.






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






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






50. A glider designed for sustained flight.
