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






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






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






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






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






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






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






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






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






11. Robotic aircraft - used extensively by the military.






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






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






14. Design machines that fly.






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






16. 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.






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






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






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






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






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






22. Aircraft speeds between Mach 5 and 10.






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






24. To set or thrust in motion.






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






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






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






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






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






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






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






32. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






45. A glider designed for sustained flight.






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






47. Aircraft speeds between Mach 10 and 25.






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






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






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