Tension on the cable, as a whole results, in pressure from the outer layer to each successive inner layer, causing normal forces between the wires. Sliding friction between the wires is proportional to the normal force and acts along the line of contact between the wires, shown by the dotted lines. Figure Legend:

Rev. 2013;65(1):010801-010801-18. doi:10.1115/1.4023489 Relationship between bending stiffness and curvature; bending stiffness is constant and maximum with minimal curvature when wires are not sliding against one another. Once the wires begin to slip, they enter the transition state, where some wires are slipping and some are sticking; K slip is the critical curvature that represents the average curvature between stick and slip states. When the cable experiences high curvature, all wires have slipped and the bending stiffness approaches the minimum. Figure Legend:
