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






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






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






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






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






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






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






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






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






11. Aircraft speeds between Mach 10 and 25.






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






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






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






16. Aircraft speeds under Mach 1.






17. 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.






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






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






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






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






22. The ratio of inertial forces to viscous forces.






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






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






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






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






27. 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.






28. Aircraft speeds between Mach 5 and 10.






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






30. 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.






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






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






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






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






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






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






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






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






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






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






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






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






43. Design machines that fly.






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






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






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






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






48. 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.






49. To set or thrust in motion.






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