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






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






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






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






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






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






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






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






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






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






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






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






14. 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.






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






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






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






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






19. The ratio of inertial forces to viscous forces.






20. 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.






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






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






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






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






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






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






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






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






29. Aircraft speeds under Mach 1.






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






31. 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.






32. Out of its own accord - an aircraft eventually returns to and remains at its equilibrium position over a period of time.






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






34. A glider designed for sustained flight.






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






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






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






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






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






40. Aircraft speeds between Mach 5 and 10.






41. 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.






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






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






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






45. Robotic aircraft - used extensively by the military.






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






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






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






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