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






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






3. A glider designed for sustained flight.






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






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






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






7. Aircraft speeds between Mach 5 and 10.






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






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






10. Aircraft speeds under Mach 1.






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






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






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






14. Robotic aircraft - used extensively by the military.






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






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






17. 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.






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






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






20. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






32. 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.






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






34. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






41. To set or thrust in motion.






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






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






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






45. Design machines that fly.






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






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






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






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






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