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 ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






19. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






30. 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.






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






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






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






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






35. Aircraft speeds between Mach 1 and 5.






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. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






43. Aircraft speeds between Mach 10 and 25.






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






45. To set or thrust in motion.






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






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






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






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






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