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 relationship between the length and width of a wing.






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






3. Aircraft speeds between Mach 1 and 5.






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






5. 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.






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






7. Aircraft speeds between Mach 5 and 10.






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






9. A glider designed for sustained flight.






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






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






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






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






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






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






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






17. Design machines that fly.






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






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






20. The ratio of inertial forces to viscous forces.






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






22. Robotic aircraft - used extensively by the military.






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






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






25. 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.






26. 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.






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






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






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






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






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






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






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






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






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






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






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






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






39. To set or thrust in motion.






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






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






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






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






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






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






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






47. Aircraft speeds under Mach 1.






48. 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.






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






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