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






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






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






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






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






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






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






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






9. Design machines that fly.






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






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






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






13. To set or thrust in motion.






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






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






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






17. Aircraft speeds between Mach 1 and 5.






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






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






20. A glider designed for sustained flight.






21. Aircraft speeds between Mach 5 and 10.






22. 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.






23. 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.






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






25. The ratio of inertial forces to viscous forces.






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






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






28. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






48. Robotic aircraft - used extensively by the military.






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






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