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. Aircraft speeds between Mach 1 and 5.






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






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






4. Aircraft speeds under Mach 1.






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






6. 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.






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






8. 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.






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






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






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






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






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






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






16. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.






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






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






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






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






21. To set or thrust in motion.






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






23. Design machines that fly.






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






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






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






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






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






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






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






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






32. The ratio of inertial forces to viscous forces.






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






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






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






36. A glider designed for sustained flight.






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






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






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






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






41. 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.






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






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






44. 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.






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






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






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






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






49. Aircraft speeds between Mach 5 and 10.






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