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






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






4. 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.






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






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






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






16. 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.






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






22. Robotic aircraft - used extensively by the military.






23. To set or thrust in motion.






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






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






26. 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.






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






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






29. Aircraft speeds under Mach 1.






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






31. 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.






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






33. Design machines that fly.






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






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






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






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






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






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






44. Aircraft speeds between Mach 1 and 5.






45. The ratio of inertial forces to viscous forces.






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






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






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






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






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