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






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






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






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






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






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






7. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






17. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






25. A glider designed for sustained flight.






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






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






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






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






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






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






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






33. 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.






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






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






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






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






38. 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.






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






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






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






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






43. Design machines that fly.






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






45. 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.






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






47. Aircraft speeds between Mach 1 and 5.






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






49. To set or thrust in motion.






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