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






2. 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.






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






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






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






6. 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.






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






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






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






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






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






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






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






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






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






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






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






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






19. The ratio of inertial forces to viscous forces.






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






21. Aircraft speeds between Mach 5 and 10.






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






23. To set or thrust in motion.






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






25. Aircraft speeds between Mach 1 and 5.






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






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






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






29. 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.






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






31. Design machines that fly.






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






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






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






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






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






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






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






39. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






49. 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.






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