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






2. To set or thrust in motion.






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






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






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






6. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






12. Design machines that fly.






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






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






15. 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.






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






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






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






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






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






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






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






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






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






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






26. 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.






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






28. 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.






29. Aircraft speeds between Mach 10 and 25.






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






31. 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.






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






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






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






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






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






37. 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.






38. A glider designed for sustained flight.






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






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






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






42. Aircraft speeds under Mach 1.






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






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






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






46. Robotic aircraft - used extensively by the military.






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






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






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






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