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






2. Robotic aircraft - used extensively by the military.






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






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






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






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






7. The ratio of inertial forces to viscous forces.






8. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






16. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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. 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.






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






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






28. A glider designed for sustained flight.






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






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






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






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






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






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






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






37. Aircraft speeds between Mach 1 and 5.






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






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






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






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






42. To set or thrust in motion.






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






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






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






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






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






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






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






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