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






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






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






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






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






6. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






17. Robotic aircraft - used extensively by the military.






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






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






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






21. The ratio of inertial forces to viscous forces.






22. 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.






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






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






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






26. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






32. 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.






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






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






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






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






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






38. Aircraft speeds between Mach 10 and 25.






39. Aircraft speeds under Mach 1.






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






41. 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.






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






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






44. Aircraft speeds between Mach 1 and 5.






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






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






47. To set or thrust in motion.






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






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






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