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






2. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






10. Aircraft speeds under Mach 1.






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






12. Design machines that fly.






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






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






15. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






30. A glider designed for sustained flight.






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






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






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






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






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






36. The angle formed by the wing chord line and the relative wind.






37. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






50. 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.
