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






2. To set or thrust in motion.






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






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






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






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






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






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






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






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






12. Aircraft speeds between Mach 10 and 25.






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






14. 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.






15. 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.






16. 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.






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






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






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






20. The ratio of inertial forces to viscous forces.






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






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






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






24. Aircraft speeds between Mach 5 and 10.






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






26. Aircraft speeds between Mach 1 and 5.






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






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






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






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






31. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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