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






2. A glider designed for sustained flight.






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






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






5. Aircraft speeds between Mach 1 and 5.






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






7. Aircraft speeds under Mach 1.






8. 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.






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






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






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






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






13. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






20. 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.






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






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






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






24. 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.






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






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






27. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






40. 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.






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






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






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






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






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






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






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






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






49. To set or thrust in motion.






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