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






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






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






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






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






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






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






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






9. 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.






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






11. Robotic aircraft - used extensively by the military.






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






13. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






21. Design machines that fly.






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






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






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






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






26. To set or thrust in motion.






27. The ratio of inertial forces to viscous forces.






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






29. 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.






30. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






38. Aircraft speeds under Mach 1.






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






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






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






42. 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.






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






44. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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