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






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






3. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






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






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






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






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






29. Robotic aircraft - used extensively by the military.






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






31. 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.






32. 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.






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






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






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






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






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






38. The ratio of inertial forces to viscous forces.






39. A glider designed for sustained flight.






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






41. Aircraft speeds between Mach 10 and 25.






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






43. To set or thrust in motion.






44. Aircraft speeds under Mach 1.






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






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






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






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






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






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