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






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






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






4. Robotic aircraft - used extensively by the military.






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






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






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






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






9. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






23. 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.






24. 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.






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






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






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






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






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






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






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






32. To set or thrust in motion.






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






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






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






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






37. The ratio of inertial forces to viscous forces.






38. Aircraft speeds between Mach 5 and 10.






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






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






41. 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.






42. Design machines that fly.






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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