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






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






3. 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.






4. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






15. Design machines that fly.






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






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






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






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






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






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






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






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






24. Aircraft speeds under Mach 1.






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






26. To set or thrust in motion.






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






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






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






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






31. Aircraft speeds between Mach 5 and 10.






32. Aircraft speeds between Mach 1 and 5.






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






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






35. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






46. 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.






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






48. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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