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. Aircraft speeds between Mach 10 and 25.






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






3. Aircraft speeds between Mach 5 and 10.






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






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






6. A glider designed for sustained flight.






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






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






18. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






29. Robotic aircraft - used extensively by the military.






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






31. 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.






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






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






34. To set or thrust in motion.






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






36. 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.






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






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






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






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






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






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. 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.






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






45. 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.






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






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






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






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






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