Hi,
Can someone give me guide to estimate wire rope bearing strength over wood?
Thanks,

RE: Wire rope bearing
I've been checking for sheave and thimbles design and bearing load becomes very large (32ksi for 1700 tension pounds) but i realise that since i'm trying to use 1/4" steel wire rope it might be comparable to nail bearing strength under Whale and Smith idealization, leaving out the considerations of surface contact that sheave and thimble roots has, I think it may be possible to take full diameter to make contact on wood.

RE: Wire rope bearing
I'm trying to get lower pressures only (second picture) and placing wires over the wales to control bending on them (red ellipse first pic).
My question is about crushing the wales with wires ropes, when reviewing sheave design to obtain bearing pressure of the rope on my wood members the result were remarkably high for my given axial tension, this is because the small diameter of the wire and the small diameter of bending i can achieve with a wale. But i don't think that those equations are valid for this materials interface and this mostly non-dynamic case. Rather i suspect that the wire rope, while being much harder than softwood, will accommodate itself and will spread the load through all contact surface in the process. Making wood behaviour more similar to Whale & Smith's nails description, but i haven't found wood bearing resistance data for steel wires to compare this idea.

But also i'l like to refine the original topic question, it may be handy to me to know about it.
