Hey, Got some rope running through four stationary cylinders (pic below)! Now if the rope on the left hand side is pulled down with lets say 100N, I would just like to find out the force on each cylinder. common sense tells me that the force on all four cylinders will be 100N in alternating directions of course. Am I correct in assuming this? Also the tension in the rope were the blue and red lines are, would they be equal to 100N as well? Thanks for any help! I should specify that the rollers cannot actually spin or turn, so I dont know if they can be treated as pulleys Edit - Or is it something like this; http://en.wikipedia.org/wiki/Image:Pulley0.svg Where if I pull down 100N the tension in the rope at the red part is 100N and the force on the cylinder is 200N?
