If one was to make a pulley to lift something massive like a ship, I am assuming the masses involved of the ship and the counterweight, will mean decreased efficiency due to :
1. Higher friction between in the sheave and axel area.
2. larger cable/robe mass on the longer end (once the pulley moves more one dir'n)
3. larger rope causing bending around the pulley.
Questions:
1. What is the loss of efficiency with a larger pulley system requirement like this?
2. What are possible advantages of a larger pulley system in terms of efficiency? For instance, i read that a larger diameter pulley can result in a large increase in efficiency for a pulley system.
Thanks.
