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






2. Aircraft speeds between Mach 5 and 10.






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






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






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






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






7. 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.






8. The ratio of inertial forces to viscous forces.






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






10. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






22. 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.






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






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






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






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






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






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






29. 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.






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






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






32. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






40. 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.






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






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






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






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






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






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






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






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






49. To set or thrust in motion.






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