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






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






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






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






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






6. 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.






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






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






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






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






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






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






13. 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.






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






15. Robotic aircraft - used extensively by the military.






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






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






18. Aircraft speeds under Mach 1.






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






20. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






38. A glider designed for sustained flight.






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






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






41. To set or thrust in motion.






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






43. 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.






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






45. Aircraft speeds between Mach 1 and 5.






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






47. Design machines that fly.






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






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






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