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






2. Robotic aircraft - used extensively by the military.






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






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






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






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






7. Aircraft speeds between Mach 1 and 5.






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






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






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






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






12. Aircraft speeds between Mach 5 and 10.






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






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






15. Design machines that fly.






16. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






23. The ratio of inertial forces to viscous forces.






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






25. 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.






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






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






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






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






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






31. Aircraft speeds under Mach 1.






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






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






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






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






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






37. 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.






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






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






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






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






42. A glider designed for sustained flight.






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






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






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






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






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






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






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






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