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






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






3. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






12. 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.






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






14. Aircraft speeds between Mach 10 and 25.






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






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






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






18. 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.






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






20. 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.






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






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






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






24. Aircraft speeds between Mach 5 and 10.






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






26. 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.






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






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






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






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






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






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






33. Aircraft speeds between Mach 1 and 5.






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






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






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






37. To set or thrust in motion.






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






39. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






48. A glider designed for sustained flight.






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






50. The ratio of inertial forces to viscous forces.
