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 part of the airfoil that meets the airflow first.






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






3. Design machines that fly.






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






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






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






7. 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.






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






9. A glider designed for sustained flight.






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






12. Aircraft speeds between Mach 1 and 5.






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






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






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






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






17. 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.






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






19. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






28. 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.






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






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






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






32. Aircraft speeds between Mach 5 and 10.






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






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






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






36. Robotic aircraft - used extensively by the military.






37. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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