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






2. To set or thrust in motion.






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






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






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






6. 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.






7. Aircraft speeds under Mach 1.






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






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






10. The ratio of inertial forces to viscous forces.






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






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






13. Design machines that fly.






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






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






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






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






18. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






29. Aircraft speeds between Mach 1 and 5.






30. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






38. 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.






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






50. 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.
