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






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






3. 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.






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






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






6. Aircraft speeds under Mach 1.






7. 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.






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






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






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






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






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






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






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






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






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






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






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






19. Aircraft speeds between Mach 5 and 10.






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






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






22. To set or thrust in motion.






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






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






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






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






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






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






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






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






31. 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.






32. 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.






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






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






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






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






37. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






43. A glider designed for sustained flight.






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






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






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






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






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






49. Robotic aircraft - used extensively by the military.






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