Pulleys & Rope Efficiency Calculator
This mechanical engineering calculator is used to calculate the efficiency of the first, second , third or more pulley system with rope or cable.
Block and tackle Efficiency approximation Formula:
A block and tackle is a system of two or more pulleys with a rope or cable threaded between them.Block and tackle - efficiency approximation(with friction factor) is calculated by using below formula
η - mechanical efficiency of the system
K -Sheave friction factor
N- ideal mechanical advantage of the system
s - number of sheaves
