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






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






3. Aircraft speeds under Mach 1.






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






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






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






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






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






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






10. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.






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






12. A glider designed for sustained flight.






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






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






15. To set or thrust in motion.






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






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






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






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






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






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






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






23. Design machines that fly.






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






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






26. Robotic aircraft - used extensively by the military.






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






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






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






30. 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.






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






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






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






34. 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.






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






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






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






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






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






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






41. The ratio of inertial forces to viscous forces.






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






43. Aircraft speeds between Mach 1 and 5.






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






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






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






49. Aircraft speeds between Mach 10 and 25.






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