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






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






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






4. 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.






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






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






7. Design machines that fly.






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






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






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






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






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






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






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






15. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 1 and 5.






25. To set or thrust in motion.






26. 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.






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






28. Aircraft speeds under Mach 1.






29. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






40. 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.






41. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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