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






2. To set or thrust in motion.






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






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






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






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






7. 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.






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






9. 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.






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






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






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






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






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






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






16. The ratio of inertial forces to viscous forces.






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






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






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






20. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






31. Aircraft speeds under Mach 1.






32. Aircraft speeds between Mach 10 and 25.






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






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






35. Robotic aircraft - used extensively by the military.






36. 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.






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






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






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






40. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






49. Design machines that fly.






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