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 glider designed for sustained flight.






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






3. 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.






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






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






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






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






8. 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.






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






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






11. The ratio of inertial forces to viscous forces.






12. To set or thrust in motion.






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






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






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






16. 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.






17. Robotic aircraft - used extensively by the military.






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






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






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






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






22. 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.






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






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






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






26. Aircraft speeds between Mach 1 and 5.






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






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






29. Aircraft speeds between Mach 5 and 10.






30. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. Aircraft speeds under Mach 1.






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






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






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