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






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






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






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






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






6. The common reference point for the three axes of the aircraft.






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






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






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






10. 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.






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






12. The ratio of inertial forces to viscous forces.






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






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






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






16. To set or thrust in motion.






17. A glider designed for sustained flight.






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






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






20. Design machines that fly.






21. Aircraft speeds between Mach 10 and 25.






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






23. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






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






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






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






28. 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.






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






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






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






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






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






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






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






36. 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.






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






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






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






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






41. Robotic aircraft - used extensively by the military.






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






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






44. Aircraft speeds under Mach 1.






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






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






47. Aircraft speeds between Mach 5 and 10.






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






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






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