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 study or practice of travel through the air.






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






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






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






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






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






14. 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.






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






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






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






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






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






20. To set or thrust in motion.






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






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






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






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






25. Aircraft speeds between Mach 10 and 25.






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






27. 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.






28. Aircraft speeds under Mach 1.






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






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






31. 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.






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






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






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






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






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






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






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






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






40. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






49. Aircraft speeds between Mach 5 and 10.






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