A little help with rope diameter.

[watereyes]

I have a polypropylene rope, its diameter is 8mm, or 0.315 inch. Would that work for full suspension hanging? Thank you.

It depends on your weight. 8mm is very thin for full suspension

I'm 50 kg.

I would use 10mm if I was you it would not cout that deep into your neck and it would be a bit safer

I see. It's a really soft rope tho

But the thinner the more it will hurt cause it cuts deeper into your neck as neccessary.

According to this, the average tensile strength of polypropylene is 35,7MPa. I will consider 30MPa. If the diameter is 8mm, the area is around 50mm², so, it can handle about 1500N or 150kg without breaking. But don't trust me, my head is a bit heavy right now and I may have miscalculated it.

The post above made an important consideration as well.

The packaging says ~600kg.

Is the rope made of several twisted fibers? The arrangement can make it handle greater loads.

Yes, it is

I am planning on using full suspension. My rope is 5/8" ( about 16 mm), made from hemp. It is soft and strong, similar to the rope used in executions. I was able to purchase it from a boating supply. From what I had read synthetic materials have too much stretch to work well which is why I went with the hemp.

they have too much stretch for a long drop I think. Short drop or partial should be fine.

Rope is designed to handle more 50kg and more, I'd say well over 120kg would be max that so you'll be fine.
I have a climbing rope, good wide, will take my body.
It takes a lot to commit ctb by rope. Bravery in the face of fear pain SI but then PEACE. Once you're ready and if not fine it's fine, all here for you
