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 straight line through the center of gravity of the aircraft and at 90






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






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






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






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






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






7. 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.






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






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






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






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






12. A glider designed for sustained flight.






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






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






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






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






17. 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.






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






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






20. Aircraft speeds between Mach 5 and 10.






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






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






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






24. 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.






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






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






27. Robotic aircraft - used extensively by the military.






28. Aircraft speeds between Mach 10 and 25.






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






30. The ratio of inertial forces to viscous forces.






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






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






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






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






35. 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.






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






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






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






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






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






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






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






43. To set or thrust in motion.






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






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






46. 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.






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






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






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






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