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 outline shape of a wing when viewed from above.






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






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






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






5. 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.






6. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






13. The ratio of inertial forces to viscous forces.






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






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






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






17. A glider designed for sustained flight.






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






19. Aircraft speeds between Mach 1 and 5.






20. 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.






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






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






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






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






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






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






27. 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.






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






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






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






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






32. 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.






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






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






35. Aircraft speeds under Mach 1.






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






37. Design machines that fly.






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






39. Aircraft speeds between Mach 5 and 10.






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






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






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






43. 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.






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






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






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






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






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






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






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