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 rate at which temperature decreases with an increase in altitude.






2. 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.






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






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






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






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






7. A glider designed for sustained flight.






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






9. 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.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






27. Design machines that fly.






28. Aircraft speeds between Mach 5 and 10.






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






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






31. To set or thrust in motion.






32. Aircraft speeds under Mach 1.






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






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






35. The ratio of inertial forces to viscous forces.






36. 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.






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






38. 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.






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






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






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






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






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






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






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






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






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






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






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






50. Robotic aircraft - used extensively by the military.
