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. Robotic aircraft - used extensively by the military.






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






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






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






5. 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.






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






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






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






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






10. The written text of a play - film - or broadcast.






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






12. Design machines that fly.






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






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






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






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






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






18. Aircraft speeds under Mach 1.






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






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






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






22. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






32. 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.






33. Aircraft speeds between Mach 5 and 10.






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






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






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






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






38. 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.






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






40. 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.






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






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






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






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






45. 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.






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






47. The ratio of inertial forces to viscous forces.






48. A glider designed for sustained flight.






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






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