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






2. A glider designed for sustained flight.






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






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






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






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. Aircraft speeds under Mach 1.






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






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






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






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






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






13. To set or thrust in motion.






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






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






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






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






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






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






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






25. 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.






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






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






28. Aircraft speeds between Mach 5 and 10.






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






30. 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.






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






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






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






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






35. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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