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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






16. To set or thrust in motion.






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






18. 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.






19. Design machines that fly.






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






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






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






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






24. 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.






25. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






34. Robotic aircraft - used extensively by the military.






35. Aircraft speeds under Mach 1.






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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