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






2. Robotic aircraft - used extensively by the military.






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






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






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






7. 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.






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






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






10. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






19. Design machines that fly.






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






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






22. 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.






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






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






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






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






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






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






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






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






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






32. Aircraft speeds between Mach 1 and 5.






33. Aircraft speeds between Mach 5 and 10.






34. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






47. Aircraft speeds between Mach 10 and 25.






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






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






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