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






3. Design machines that fly.






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






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






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






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






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






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






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






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






12. The ratio of inertial forces to viscous forces.






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






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






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






16. Aircraft speeds between Mach 10 and 25.






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






18. A glider designed for sustained flight.






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






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






21. 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.






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






23. 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.






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






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






26. Aircraft speeds under Mach 1.






27. To set or thrust in motion.






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






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






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






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






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






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






34. Aircraft speeds between Mach 5 and 10.






35. 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.






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






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






38. 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.






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






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






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






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






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






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






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






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






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






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






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






50. Robotic aircraft - used extensively by the military.
