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 rate at which temperature decreases with an increase in altitude.






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






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






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






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






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






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






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






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






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






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






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






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






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






15. Aircraft speeds between Mach 10 and 25.






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






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






18. To set or thrust in motion.






19. Robotic aircraft - used extensively by the military.






20. Aircraft speeds between Mach 5 and 10.






21. 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.






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






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






24. A glider designed for sustained flight.






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






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






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






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






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






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






31. 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.






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






33. Aircraft speeds under Mach 1.






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






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






36. 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.






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






38. 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.






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






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






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






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






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






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






45. 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.






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






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






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






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






50. Design machines that fly.
