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






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






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






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






5. Aircraft speeds under Mach 1.






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






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






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






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






10. A glider designed for sustained flight.






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






12. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. 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.






28. Aircraft speeds between Mach 1 and 5.






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. Robotic aircraft - used extensively by the military.






32. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






38. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






47. 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.






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






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






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