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






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






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






4. To set or thrust in motion.






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






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






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






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






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






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






11. Design machines that fly.






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






13. Aircraft speeds between Mach 1 and 5.






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






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






16. Forces and moments on the body caused by a disturbance tend initially to return the body toward its equilibrium position.






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






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






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






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






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






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






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






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






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






26. 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.






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






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






29. 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.






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






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






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






33. Robotic aircraft - used extensively by the military.






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






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






36. 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.






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






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






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






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






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






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






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






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






45. 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.






46. Aircraft speeds under Mach 1.






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






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






49. The ratio of inertial forces to viscous forces.






50. Aircraft speeds between Mach 5 and 10.
