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






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






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






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






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






6. Robotic aircraft - used extensively by the military.






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






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






9. To set or thrust in motion.






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






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






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






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






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






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






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






17. A glider designed for sustained flight.






18. 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.






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






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






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






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






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






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






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






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






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






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






29. 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.






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






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






32. 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.






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






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






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






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






37. Aircraft speeds between Mach 5 and 10.






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






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






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






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






42. Aircraft speeds under Mach 1.






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






44. 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.






45. 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.






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






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






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






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






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