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






2. Aircraft speeds between Mach 1 and 5.






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






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






6. Aircraft speeds between Mach 10 and 25.






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






8. A glider designed for sustained flight.






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






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






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






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






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






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






15. Robotic aircraft - used extensively by the military.






16. 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.






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






18. Design machines that fly.






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






20. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






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






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






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






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






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






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






42. To set or thrust in motion.






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






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






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






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






47. Aircraft speeds under Mach 1.






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






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






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