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






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






3. A glider designed for sustained flight.






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






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






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






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






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






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






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






11. 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.






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






13. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






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






16. Robotic aircraft - used extensively by the military.






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






18. The ratio of inertial forces to viscous forces.






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






20. Aircraft speeds between Mach 1 and 5.






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






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






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






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






25. 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.






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






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






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






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






30. Aircraft speeds between Mach 10 and 25.






31. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. To set or thrust in motion.






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






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






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