Answer 1

Answer:

Block & Tackle efficiency approximation calculator - formula & step by step calculation to find the efficiency of the system of two or more pulleys with rope or cable connected between them. η = (KN - 1)/[(ks x N) x (K - 1)].

I HOPE IT WILL SURELY HELP:)

Answer 2

Answer:

The efficiency depends upon the mass of lower block; therefore efficiency is reduced due to the weight of the lower block of pulleys.
