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 straight line through the center of gravity of the aircraft and at 90






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






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






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






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






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






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






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






9. Robotic aircraft - used extensively by the military.






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






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






12. 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.






13. 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.






14. To set or thrust in motion.






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






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






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






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






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






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






21. 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.






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






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






24. Aircraft speeds between Mach 5 and 10.






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






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






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






28. A glider designed for sustained flight.






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






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






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






33. 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.






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






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






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






37. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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