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






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






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






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






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






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






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






8. 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.






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






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






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






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






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






14. Design machines that fly.






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






16. The ratio of inertial forces to viscous forces.






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






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






19. 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.






20. 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.






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






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






23. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






33. Robotic aircraft - used extensively by the military.






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






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






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






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






38. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






48. 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.






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






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