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






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






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






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






5. The ratio of inertial forces to viscous forces.






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






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






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






9. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 5 and 10.






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






22. A glider designed for sustained flight.






23. 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.






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






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






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






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






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






29. 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.






30. 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.






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






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






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






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






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






36. Aircraft speeds between Mach 10 and 25.






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






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






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






40. To set or thrust in motion.






41. Aircraft speeds between Mach 1 and 5.






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






43. 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.






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






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






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






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






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






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






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