Subject : engineering
Instructions:
  • Answer 50 questions in 20 minutes. 2 minutes extra for reading the instructions.
  • 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. A straight line through the center of gravity of the aircraft and at 90






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






18. 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.






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






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






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






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






23. 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.






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






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






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






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






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






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






30. Design machines that fly.






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






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






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






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






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






37. The ratio of inertial forces to viscous forces.






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






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






40. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






46. Aircraft speeds under Mach 1.






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






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






49. A glider designed for sustained flight.






50. To set or thrust in motion.
