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






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






3. Design machines that fly.






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






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






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






7. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






18. Aircraft speeds between Mach 1 and 5.






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






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






21. 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.






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






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






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






25. A glider designed for sustained flight.






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






27. 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.






28. The ratio of inertial forces to viscous forces.






29. Aircraft speeds between Mach 5 and 10.






30. 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.






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






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






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






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






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






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






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






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






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






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






41. Aircraft speeds under Mach 1.






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






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






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






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






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






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






48. To set or thrust in motion.






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






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