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






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






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






4. Design machines that fly.






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






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






15. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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. The ratio of inertial forces to viscous forces.






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






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






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






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






32. 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.






33. Aircraft speeds under Mach 1.






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






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






36. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






47. 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.






48. Robotic aircraft - used extensively by the military.






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






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