Subject : engineering
Instructions:
  • Answer 50 questions in 30 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. Design machines that fly.






2. 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.






3. To set or thrust in motion.






4. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






21. Robotic aircraft - used extensively by the military.






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






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






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






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






26. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






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 force caused by the gravitational attraction of the Earth.






42. 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.






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






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






45. A glider designed for sustained flight.






46. The ratio of inertial forces to viscous forces.






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






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






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






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