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






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






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






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






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






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






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






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






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






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






11. Aircraft speeds between Mach 10 and 25.






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






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






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






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






16. Robotic aircraft - used extensively by the military.






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






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






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






20. Aircraft speeds between Mach 1 and 5.






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






22. To set or thrust in motion.






23. 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.






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






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






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






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






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






29. Design machines that fly.






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






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






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






33. 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.






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






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






36. 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.






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






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






39. Aircraft speeds under Mach 1.






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






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






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






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






44. 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.






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






46. The ratio of inertial forces to viscous forces.






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 glider designed for sustained flight.






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






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