So I'm working on a little project and I know that multiple wires can hold more than just one. What I'm curious about is how much does the tensile strength go up with multiple things? Be they clamps, wires, whatever. Say one can hold 100, would two hold 200? Or is it more nuanced?

Tensile strength is a material property and does not change as you add more wires. More wires distributes the load between the additional wires, lowering the load (or more importantly, the pressure) on each wire.

More wires = Higher load carrying capacity

Interesting. What if you kept making the wires smaller and kept adding more of them?

cables also have to support their own weight, so technically two could hold slightly less than 200. look up the worlds tallest elevator (its underground). theres a limit to how deep you can make it because the longer you make the cables, the more weight the top has to support. making the cable wider (or just adding a second one) wont help in that case.
this kind of thing is probably negligible in most scenarios i imagine tho.

The most important factor is the total cross-sectional area of all of the wires (if we assume the load is distributed evenly between all the wires). That's what your load is passed through, and if the pressure (load divided by area) exceeds the tensile strength of the material at any point, that wire will snap.

Actually "snap" is the wrong word, it will yield.

Ok cool. Is there any advantage by making the wires just small enough to not snap and fitting in as many as possible? Just curious.

>anon has never heard of velcro
Whats it like growing up in a mud hut village? How do you have internet, starlink?

My village was the one that created the zipper. Would you make a bridge suspension out of velcro??

Let's say you want to use zip ties to hold something up on a wall. One zip tie holds 50 pounds. Let's say the object weighs 100. Without any other factors causing issues, would two zip ties effectively hold it up? If you add four of them that would mean each is holding up 25?

So one wire made of many small wires instead of just one big thick one? Interesting question. Anyone know if or why that would be a desirable sort of cable?

(load capacity) = (strength of weakest link) * (amount of links)

but it is a lot more nuanced
