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






2. Aircraft speeds under Mach 1.






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






4. The ratio of inertial forces to viscous forces.






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






6. 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.






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






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






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






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






11. 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.






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






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






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






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






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






17. 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.






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






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






20. Design machines that fly.






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






22. A glider designed for sustained flight.






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






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






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






26. 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.






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






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






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






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






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






32. To set or thrust in motion.






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






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






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






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






37. Aircraft speeds between Mach 5 and 10.






38. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






45. Robotic aircraft - used extensively by the military.






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






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






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






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






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