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






2. To set or thrust in motion.






3. 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.






4. Aircraft speeds between Mach 5 and 10.






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






6. 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.






7. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






21. 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.






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






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






24. 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.






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






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






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






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






29. Robotic aircraft - used extensively by the military.






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






31. The ratio of inertial forces to viscous forces.






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






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






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






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






36. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






49. Aircraft speeds between Mach 10 and 25.






50. Aircraft speeds between Mach 1 and 5.
