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 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.






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






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






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






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






6. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






12. 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.






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






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






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






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






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






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






19. A force caused by the gravitational attraction of the Earth.






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






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






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






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






25. To set or thrust in motion.






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






27. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






35. Robotic aircraft - used extensively by the military.






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






37. Aircraft speeds between Mach 10 and 25.






38. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






39. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






46. Design machines that fly.






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






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






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






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