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 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.






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






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






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






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






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






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






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






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






10. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






17. Aircraft speeds between Mach 5 and 10.






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






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






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






21. 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.






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






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






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






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






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






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






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






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






30. To set or thrust in motion.






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






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






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






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






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






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






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






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






39. 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.






40. 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.






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






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






43. Design machines that fly.






44. The ratio of inertial forces to viscous forces.






45. 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.






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






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






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






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






50. Aircraft speeds between Mach 10 and 25.
