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






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






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






4. To set or thrust in motion.






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






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






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






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






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






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






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






12. Aircraft speeds between Mach 5 and 10.






13. Design machines that fly.






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






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






16. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






27. The ratio of inertial forces to viscous forces.






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






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






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






31. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






40. Aircraft speeds between Mach 1 and 5.






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






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






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






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






45. 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.






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






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






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






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






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