Dear Advisor,

I tried to read books and searched all around before posting new topic here... I'm carying out testing a hoisting winch at load 400 kN through a system as in picture.

My problem is that due to fiber rope i only can measure exactly wire tension by a load cell installed through shackle at weight end, so is the formula in locked thread "https://www.physicsforums.com/showthread.php?t=392239" can be applied in my case to find the friction loss then i will deduct and lift an exactly weight less than 400 kN that will give me tension 400 kN at the end of pulley A, the weight of pulley B and C is pretty heavy also.

Hope someone tell me what should i need to find in this case, thanks very much
