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






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






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






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






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






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






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






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






9. Robotic aircraft - used extensively by the military.






10. Aircraft speeds between Mach 5 and 10.






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






12. 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.






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






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






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






16. 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.






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






18. 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.






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






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






21. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 10 and 25.






36. A glider designed for sustained flight.






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






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






39. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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