Rope tension
Rope tension
(OP)
Hi,
If I wind a rope on a reel with a certain force, producing a tension in the rope, is there a way to calculate what the resulting pressure or force is acting on the central tube of the reel?
I thought about using the analogy of a pressure vessel but this results in very high pressures on this tube which are not realistic.
Any pointers?
Thanks,
Dimitri.

RE: Rope tension
This is why winch makers all specify the winch's pulling power as the first wrap on the drum. Subsequent wraps will result in less force available.

The high pressures you calculate aren't, necessarily, unrealistic.

The companies that make winches for yachts, (Harken, Lewmar etc) would certainly be able to help you as this question is an important part of their design process.
