WebFeb 5, 2015 · I have read a lot of materials and forum and the radial pressure on the core is based very simple equation P=2T/Dd. "T" is line tension, "D" is the diameter of the drum and "d" is the wire rope diameter. The equation is layer sensitive; the next successive layer would change the diameter of the drum core by D'=D+2d. WebIf a rope is lying in equilibrium under tangential forces on a rough orthotropic surface then all three following conditions are satisfied: No separation – normal reaction is positive for all points of the rope curve: , …

WebThe only forces directly acting on the pulley which creates torque are the tensions. Note that ropes, and therefore tensions, are always tangential to the object and thus normal to the radius. The tensions are different on either side of the pulley because of static friction which we don't need to consider.
