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. 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.






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






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






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






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






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






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






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






9. Aircraft speeds under Mach 1.






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






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






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






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






14. 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.






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






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






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






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






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






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






21. Aircraft speeds between Mach 10 and 25.






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






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






24. Design machines that fly.






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






26. 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.






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






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






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






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






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






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






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






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






35. The ratio of inertial forces to viscous forces.






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






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






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






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






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






41. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






48. Aircraft speeds between Mach 5 and 10.






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






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