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 relationship between the length and width of a wing.






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






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






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






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






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






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






8. A glider designed for sustained flight.






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






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






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






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






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






14. 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.






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. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






23. The ratio of inertial forces to viscous forces.






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






25. To set or thrust in motion.






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






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






28. Aircraft speeds between Mach 1 and 5.






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






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






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






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






33. Aircraft speeds between Mach 5 and 10.






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






35. 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.






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






37. Aircraft speeds under Mach 1.






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






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






40. Design machines that fly.






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






43. 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.






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






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






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






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






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






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






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