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






2. Design machines that fly.






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






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






5. 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.






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






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






8. 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.






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






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






11. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. Aircraft speeds between Mach 1 and 5.






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






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






30. Robotic aircraft - used extensively by the military.






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






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






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






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






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






36. 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.






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






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






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






40. To set or thrust in motion.






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






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






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






44. The ratio of inertial forces to viscous forces.






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






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






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






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






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






50. Aircraft speeds between Mach 10 and 25.
