When the pulley is connected as shown in the figure, the tension of the line passing through the fixed pulley acts only as the force F applied without the gain of the force, but increases by twice the force as it passes through the pulley.

If the number of moving pulleys except for the fixed pulley is N, then the weight W that can be lifted by the Nth movable pulley is given by the following equation with the force F applied to the line connected to the first fixed pulley.

W = F * 2^(N)

The weight of the rope and the pulley is not considered.
