Question on pulley system and winch of helicopter ,Pulley

Jun 25, (1) A helicopter winch uses a pulley system consisiting of 4 pulleys in an upper block and 3 pulleys in a lower block teh above system results in a movement ratio of 7 If the force ratio for this system is 4 then what is the efficiency of the pulley system (2) A serach and rescue helicopter uses the above winch to rescue a person of mass 80kg from sea to a height of 25m so which is its safe .In simple science, though, we tend to use "pulley" just to mean a bunch of wheels and ropes for lifting Photos: Two types of pulleys Left: A block and tackle is a pulley-based system for lifting things, made of blocks (the wheel sections) and tackle joining them together.

Block and tackle

A block and tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads The pulleys are assembled together to form blocks and then blocks are paired so that one is fixed and one moves with the loadPulley definition is - a sheave or small wheel with a grooved rim and with or without the block in which it runs used singly with a rope or chain to change the direction and point of application of a pulling force and in various combinations to increase the applied force especially for lifting weights.
