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






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






3. Aircraft speeds between Mach 10 and 25.






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






5. Design machines that fly.






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






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






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






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






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






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






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






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






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






15. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






31. 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.






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






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






34. The ratio of inertial forces to viscous forces.






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






36. Aircraft speeds under Mach 1.






37. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






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






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






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






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






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






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






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






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






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






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






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






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






50. 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.
