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 relationship between the length and width of a wing.






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






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






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






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






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






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






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






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






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






11. 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.






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






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






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






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






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






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






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






19. Aircraft speeds between Mach 1 and 5.






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






21. 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.






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






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






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






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






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






27. 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.






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






29. The ratio of inertial forces to viscous forces.






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






31. A glider designed for sustained flight.






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






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






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






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






36. Aircraft speeds between Mach 10 and 25.






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






38. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






44. 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.






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






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






47. 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.






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






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






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