I'm wondering if someone could help me. I'm curious what the torque in each driven roller would be in the following picture.
![]()
Say for example I want the input tension(T1) to be 10 lbs and the output tension(T2) to be 20 pounds. Assume the radius for each driven nip is the same. Also assume there is a brake upstream somewhere. I am having difficulties in figuring out what the torque would be for each of the nips. I don't care about the speed of each nip but am only curious about the torque. I just don't understand how each nip isolates input and output tension. Any help?
