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






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






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






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






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






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






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






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






10. 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.






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






12. 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.






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






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






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






16. 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.






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






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






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






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






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






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






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






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






25. A glider designed for sustained flight.






26. 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.






27. Robotic aircraft - used extensively by the military.






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






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






30. Aircraft speeds between Mach 10 and 25.






31. The ratio of inertial forces to viscous forces.






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






33. Aircraft speeds between Mach 5 and 10.






34. Aircraft speeds under Mach 1.






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






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






37. 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.






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






39. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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