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






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






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






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






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






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






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






8. Aircraft speeds between Mach 10 and 25.






9. Aircraft speeds under Mach 1.






10. Design machines that fly.






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






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






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






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






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






16. To set or thrust in motion.






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






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






19. 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.






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






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






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






23. 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.






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






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






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






27. Aircraft speeds between Mach 1 and 5.






28. Aircraft speeds between Mach 5 and 10.






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






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






31. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






39. 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.






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






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






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






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






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






45. 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.






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






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






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






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






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