The german wiki article has an paragraph about an analogue effect in mechanics in which adding an additional spring to support a hanging weight can causes the weight to hang lower than before. Which I found quite interesting.

- schoen 10y agoThe article describes a weight initially hanging from two strong springs (blue) and two weak springs (yellow). The subsequent addition of the strong red spring in the indicated position will, according to the article's calculations, make the weight hang lower overall. I also find that pretty counterintuitive! Edit: the explanation given is that the red spring redistributes forces so that more force is applied to the weak springs and less force to the strong springs, causing an overall greater total extension.
