Pulley mechanical advantage API

Computes the ideal mechanical advantage (number of supporting rope segments) and the effort force to lift a load, with an efficiency-adjusted real effort and rope pulled per unit of load rise. Answers 'What is the mechanical advantage of a block and tackle?', 'How much force to lift a load with this pulley system?'.
