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






2. 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.






3. 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.






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






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






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






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






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






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






10. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






19. A glider designed for sustained flight.






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






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






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






23. The ratio of inertial forces to viscous forces.






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






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






26. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






34. 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.






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






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






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






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






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






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






41. Design machines that fly.






42. 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.






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






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






45. Robotic aircraft - used extensively by the military.






46. Aircraft speeds under Mach 1.






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






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






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






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