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






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






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






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






5. 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.






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






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






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






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






10. 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.






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






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






13. Design machines that fly.






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






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






16. 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.






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






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






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






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






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






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






24. A glider designed for sustained flight.






25. To set or thrust in motion.






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






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






28. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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






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






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






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






49. Aircraft speeds under Mach 1.






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