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






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






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






4. 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.






5. 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.






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






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






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






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






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






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






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






13. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






21. Design machines that fly.






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






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






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






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






26. The ratio of inertial forces to viscous forces.






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






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






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






30. To set or thrust in motion.






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






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






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






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






35. Aircraft speeds between Mach 10 and 25.






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. Aircraft speeds between Mach 1 and 5.






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






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






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






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






42. A glider designed for sustained flight.






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






44. 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.






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






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






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






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






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






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