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






2. 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.






3. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






9. Aircraft speeds between Mach 1 and 5.






10. To set or thrust in motion.






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






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






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






14. Aircraft speeds under Mach 1.






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






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






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






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






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






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






21. 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.






22. Design machines that fly.






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






24. Aircraft speeds between Mach 10 and 25.






25. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






33. 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.






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






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






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






37. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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