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






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






3. Robotic aircraft - used extensively by the military.






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






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






6. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






14. Aircraft speeds between Mach 10 and 25.






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






16. 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.






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






18. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






33. To set or thrust in motion.






34. The art and science of designing - building - and operating manned or unmanned space objects






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






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






37. 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.






38. 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.






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






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






41. 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.






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






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






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






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






46. Design machines that fly.






47. 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.






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






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






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