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. Robotic aircraft - used extensively by the military.






2. 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.






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






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






5. 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.






6. 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.






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






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






10. 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.






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






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






13. Aircraft speeds under Mach 1.






14. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






23. A glider designed for sustained flight.






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






25. A short - easily- remembered slogan - verse - or tune.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. Aircraft speeds between Mach 10 and 25.






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






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






49. Design machines that fly.






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