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 under Mach 1.






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






3. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. To set or thrust in motion.






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






28. A glider designed for sustained flight.






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






30. 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.






31. 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.






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






33. Design machines that fly.






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






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






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






48. Aircraft speeds between Mach 1 and 5.






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






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