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. To set or thrust in motion.






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






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






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






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






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






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






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






9. The ratio of inertial forces to viscous forces.






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






11. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






20. 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.






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






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






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






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






25. A glider designed for sustained flight.






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






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






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






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






30. Robotic aircraft - used extensively by the military.






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






32. Aircraft speeds between Mach 10 and 25.






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






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






35. Aircraft speeds between Mach 5 and 10.






36. Aircraft speeds between Mach 1 and 5.






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






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






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






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






42. Design machines that fly.






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






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






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






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






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






48. 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.






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






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