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






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






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






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






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






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






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






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






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






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






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






12. To set or thrust in motion.






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






14. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






22. Design machines that fly.






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






24. 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.






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






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






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






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






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






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






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






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






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






34. 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.






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






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






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






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






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






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






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






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






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






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






45. 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.






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






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






48. Aircraft speeds between Mach 5 and 10.






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






50. Robotic aircraft - used extensively by the military.
