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






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






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






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






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






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






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






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






10. 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.






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






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






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






14. Aircraft speeds between Mach 10 and 25.






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






16. 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.






17. Aircraft speeds under Mach 1.






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






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






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






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






22. Aircraft speeds between Mach 1 and 5.






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






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






25. The outline shape of a wing when viewed from above.






26. To set or thrust in motion.






27. 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.






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






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






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






31. A glider designed for sustained flight.






32. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. 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.






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






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






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