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






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






3. 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.






4. Robotic aircraft - used extensively by the military.






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






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






7. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






14. 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.






15. 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.






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






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






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






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






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






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






22. Design machines that fly.






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






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






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






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






27. Aircraft speeds between Mach 5 and 10.






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






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






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






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






32. Aircraft speeds under Mach 1.






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






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






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






36. 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.






37. 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.






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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