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






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






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






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






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






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






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






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






9. Aircraft speeds under Mach 1.






10. 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.






11. Aircraft speeds between Mach 5 and 10.






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






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






14. Design machines that fly.






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






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






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






18. To set or thrust in motion.






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






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






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






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






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






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






25. A glider designed for sustained flight.






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






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






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






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






35. 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.






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






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






38. 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.






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






40. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






49. 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.






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