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 part of the airfoil that meets the airflow first.






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






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






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






17. 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.






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






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






20. Aircraft speeds under Mach 1.






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






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






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






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






25. The ratio of inertial forces to viscous forces.






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






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






28. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






35. A glider designed for sustained flight.






36. 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.






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






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






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






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






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






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






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






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






45. Design machines that fly.






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






47. 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.






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






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






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