Stretch in Wire Ropes.						Back to home page www.tradeproducts.com.au
Stretch is a characteristic of all wire ropes, intitially as permanent stretch when the load is first applied and the individual wires bed down, and then as conventional elastic stretch within the wires. Where stretch is critical to the application, initial stretch can be accounted for with cables pre-tensioned or pre-stressed during swaging and cable manufacturing. Elastic stretch can be calculated by the following formula:		Elastic stretch (mm) = W x L / E x A  where:                                                                                                         W = Applied load (kN)                                  L = cable length (mm)                           E = strand modulus (kN/ mm2)                       A = Area of cable= D2 X π / 4                     D = Nominal diameter of cable (mm)
