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






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






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






4. 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.






5. A glider designed for sustained flight.






6. 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.






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






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






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






10. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






24. 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.






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






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






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






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






29. Aircraft speeds between Mach 1 and 5.






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






31. Robotic aircraft - used extensively by the military.






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






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






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






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






36. To set or thrust in motion.






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






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






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






44. The art and science of designing - building - and operating manned or unmanned space objects






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






46. Design machines that fly.






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






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






49. 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.






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