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






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






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






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






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






6. The ratio of inertial forces to viscous forces.






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






8. 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.






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






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






11. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






18. Aircraft speeds between Mach 10 and 25.






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






20. 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.






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






22. A glider designed for sustained flight.






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






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






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






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






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






28. Robotic aircraft - used extensively by the military.






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






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






31. 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.






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






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






34. Aircraft speeds under Mach 1.






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






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






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






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






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






40. To set or thrust in motion.






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






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






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






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






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






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






47. 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.






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






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






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