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






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






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






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






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






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






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






8. Robotic aircraft - used extensively by the military.






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






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






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






13. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.






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






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






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






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






18. A glider designed for sustained flight.






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






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






21. Aircraft speeds under Mach 1.






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






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






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






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






26. Aircraft speeds between Mach 10 and 25.






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






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






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






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






31. Aircraft speeds between Mach 1 and 5.






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






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






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






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






36. 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.






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






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






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






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






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






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






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






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






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






46. 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.






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






48. 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.






49. To set or thrust in motion.






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