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






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






3. Aircraft speeds under Mach 1.






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






5. The ratio of inertial forces to viscous forces.






6. 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.






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






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






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






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






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






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






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






14. 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.






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






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






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






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






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






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






21. To set or thrust in motion.






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






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






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






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






26. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






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






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






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






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






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






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






34. 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.






35. Robotic aircraft - used extensively by the military.






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






41. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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