Description
The pulley joint is connected to two bodies and two fixed ground points. The pulley supports a ratio such that: length1 ratio * length2 <= constant Yes, the force transmitted is scaled by the ratio. The pulley also enforces a maximum length limit on both sides. This is useful to prevent one side of the pulley hitting the top.
