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. Robotic aircraft - used extensively by the military.






2. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






13. Aircraft speeds between Mach 10 and 25.






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






15. Design machines that fly.






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






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






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






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






20. 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.






21. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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. 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.






43. The ratio of inertial forces to viscous forces.






44. 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.






45. A glider designed for sustained flight.






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






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






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






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






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