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 study or practice of travel through the air.






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






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






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






6. Aircraft speeds under Mach 1.






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






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






9. Design machines that fly.






10. 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.






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






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






13. 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.






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






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






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






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






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






19. To set or thrust in motion.






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






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






22. Aircraft speeds between Mach 1 and 5.






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






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






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






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






27. 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.






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






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






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






31. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






41. The ratio of inertial forces to viscous forces.






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






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






44. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






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






46. Aircraft speeds between Mach 10 and 25.






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






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






49. 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.






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