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 force caused by the gravitational attraction of the Earth.






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






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






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






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






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






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






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






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






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






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






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






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






14. 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.






15. The ratio of inertial forces to viscous forces.






16. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






22. Aircraft speeds between Mach 10 and 25.






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






24. Robotic aircraft - used extensively by the military.






25. Characteristic of the aircraft that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuver.






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






27. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






35. 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.






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






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






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






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






40. 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.






41. Design machines that fly.






42. 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.






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






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






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






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






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






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






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






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