It’s notable that the prior experiments described have focused on dynamics while the strength of a knot is a question of statics. It would be interesting to see further research into the intuitive understanding of other types of static systems, such as bridges(1) or various cantilever structures, and especially other systems where the dominant forces stem from static friction like in knots.
(1) Based on some very spotty anecdotal data, I wouldn’t be surprised if many people don’t even consider the primary load-bearing structures of many bridge types as crucial to the bridge’s strength but more like purely aesthetical additions.
- bubblyworld 2y agoIs it so clear that it's a question of statics? Knots are often tied in dynamic rope (static rope will lose much more strength around a tight bend radius) and if you look at break-testing youtubers like HowNot2 the knots move a lot while they are being broken. A knot that's taken to almost breaking loads looks very different to the original knot in most cases. My impression is that a common failure mode is the rope cutting through itself, which comes down to dynamic friction and the resulting heat I think.
