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






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






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






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






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






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






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






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






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






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






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






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






13. A glider designed for sustained flight.






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






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






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






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






18. 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.






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






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






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






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






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






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






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






26. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 10 and 25.






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






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






38. 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.






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






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






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






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






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






44. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






50. 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.
