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






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






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






5. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






16. 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.






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






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






19. 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.






20. 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.






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






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






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






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






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






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






27. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






33. To set or thrust in motion.






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






35. Robotic aircraft - used extensively by the military.






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






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






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






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






40. The ratio of inertial forces to viscous forces.






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






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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