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 glider designed for sustained flight.






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






3. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






14. Robotic aircraft - used extensively by the military.






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






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






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






18. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






28. 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.






29. Aircraft speeds under Mach 1.






30. 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.






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






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






33. The ratio of inertial forces to viscous forces.






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






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






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






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






38. Aircraft speeds between Mach 5 and 10.






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






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






41. 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.






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






43. 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.






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






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






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






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






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






49. 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.






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