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






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






3. 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.






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






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






6. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






22. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






31. Aircraft speeds between Mach 5 and 10.






32. To set or thrust in motion.






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






34. 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.






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






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






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






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






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






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






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






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






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






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






45. 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.






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






47. Aircraft speeds between Mach 1 and 5.






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






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






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