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






2. The ratio of inertial forces to viscous forces.






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






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






11. The movement about the vertical axis produced by the rudder and controlled by pedals.






12. Design machines that fly.






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






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






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






16. To set or thrust in motion.






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






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






19. 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.






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






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






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






23. 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.






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






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






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






27. Aircraft speeds between Mach 5 and 10.






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






29. 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.






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






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






32. Robotic aircraft - used extensively by the military.






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






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






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






37. Aircraft speeds between Mach 1 and 5.






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






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






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






41. A glider designed for sustained flight.






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






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






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






45. Aircraft speeds under Mach 1.






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






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






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






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






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