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






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






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






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






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






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






7. A glider designed for sustained flight.






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






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






10. 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.






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






12. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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






26. The ratio of inertial forces to viscous forces.






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






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






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






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






31. Robotic aircraft - used extensively by the military.






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






33. Aircraft speeds between Mach 1 and 5.






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






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






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






37. Aircraft speeds under Mach 1.






38. Design machines that fly.






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






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






41. 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.






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






43. 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.






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






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






46. 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.






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






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






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






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