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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






18. Aircraft speeds between Mach 5 and 10.






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






20. 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.






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






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






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






24. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






32. Design machines that fly.






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






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






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






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






37. The ratio of inertial forces to viscous forces.






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






39. 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.






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






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






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






43. 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.






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






45. A glider designed for sustained flight.






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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