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






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






3. Aircraft speeds between Mach 10 and 25.






4. Design machines that fly.






5. 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.






6. To set or thrust in motion.






7. Robotic aircraft - used extensively by the military.






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






9. 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.






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






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






12. 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.






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






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






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






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






17. A glider designed for sustained flight.






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






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






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






21. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






30. Aircraft speeds between Mach 5 and 10.






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






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






33. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






49. Aircraft speeds under Mach 1.






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