If 11 parts are used in a pulley system, what happens to the mechanical advantage?

In an ideal pulley system, the mechanical advantage equals the number of rope segments supporting the moving load. Each additional segment shares the load, reducing the force you need to apply. With 11 parts, there are 11 supporting segments, so the mechanical advantage increases to 11. This means you could lift the same load with about one-eleventh of the effort, assuming no friction or pulley weight. In real-world use, friction and the mass of the rope and pulleys will reduce that ideal advantage somewhat.
