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. Aircraft speeds between Mach 1 and 5.






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






4. A glider designed for sustained flight.






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






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






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






8. Aircraft speeds between Mach 5 and 10.






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






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






11. To set or thrust in motion.






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






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






14. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






24. The ratio of inertial forces to viscous forces.






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






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






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






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






29. 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.






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






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






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






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






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






35. Aircraft speeds under Mach 1.






36. 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.






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






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






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






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






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






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






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






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






45. 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.






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






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






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






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






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