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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






18. 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.






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






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






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






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






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






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






25. Aircraft speeds between Mach 10 and 25.






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






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






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






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






30. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






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






32. Design machines that fly.






33. To set or thrust in motion.






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






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






36. 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.






37. Aircraft speeds under Mach 1.






38. The ratio of inertial forces to viscous forces.






39. A glider designed for sustained flight.






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






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






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






43. Aircraft speeds between Mach 1 and 5.






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






45. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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