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






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






4. 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.






5. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.






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






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






26. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






35. 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.






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






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






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






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






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






42. 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.






43. Aircraft speeds under Mach 1.






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






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






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






47. 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.






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






49. To set or thrust in motion.






50. The ratio of inertial forces to viscous forces.
