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






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






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






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






5. To set or thrust in motion.






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






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






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






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






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






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






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






13. Aircraft speeds between Mach 5 and 10.






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






15. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






23. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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






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






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






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






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






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






32. Design machines that fly.






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






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






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






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






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






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






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






40. Robotic aircraft - used extensively by the military.






41. 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.






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






43. 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.






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






45. 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.






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






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






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






49. Aircraft speeds under Mach 1.






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