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






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






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






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






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






6. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






13. 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.






14. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






33. A glider designed for sustained flight.






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






35. 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.






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






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






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






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






40. Aircraft speeds under Mach 1.






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






42. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






49. 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.






50. Aircraft speeds between Mach 5 and 10.
